Trait Implementations

impl<'de> Visitor<'de> for FieldVisitor

type Value = ()

The value produced by this visitor.

fn expecting(&self, formatter: &mut Formatter<'_>) -> Result

Format a message stating what data this Visitor expects to receive.

fn visit_str<E>(self, s: &str) -> Result<(), E>where E: Error,

The input contains a string. The lifetime of the string is ephemeral and it may be destroyed after this method returns.

fn visit_bool<E>(self, v: bool) -> Result<Self::Value, E>where E: Error,

The input contains a boolean.

fn visit_i8<E>(self, v: i8) -> Result<Self::Value, E>where E: Error,

The input contains an i8.

fn visit_i16<E>(self, v: i16) -> Result<Self::Value, E>where E: Error,

The input contains an i16.

fn visit_i32<E>(self, v: i32) -> Result<Self::Value, E>where E: Error,

The input contains an i32.

fn visit_i64<E>(self, v: i64) -> Result<Self::Value, E>where E: Error,

The input contains an i64.

fn visit_i128<E>(self, v: i128) -> Result<Self::Value, E>where E: Error,

The input contains a i128.

fn visit_u8<E>(self, v: u8) -> Result<Self::Value, E>where E: Error,

The input contains a u8.

fn visit_u16<E>(self, v: u16) -> Result<Self::Value, E>where E: Error,

The input contains a u16.

fn visit_u32<E>(self, v: u32) -> Result<Self::Value, E>where E: Error,

The input contains a u32.

fn visit_u64<E>(self, v: u64) -> Result<Self::Value, E>where E: Error,

The input contains a u64.

fn visit_u128<E>(self, v: u128) -> Result<Self::Value, E>where E: Error,

The input contains a u128.

fn visit_f32<E>(self, v: f32) -> Result<Self::Value, E>where E: Error,

The input contains an f32.

fn visit_f64<E>(self, v: f64) -> Result<Self::Value, E>where E: Error,

The input contains an f64.

fn visit_char<E>(self, v: char) -> Result<Self::Value, E>where E: Error,

The input contains a char.

fn visit_borrowed_str<E>(self, v: &'de str) -> Result<Self::Value, E>where E: Error,

The input contains a string that lives at least as long as the Deserializer.

fn visit_string<E>(self, v: String) -> Result<Self::Value, E>where E: Error,

The input contains a string and ownership of the string is being given to the Visitor.

fn visit_bytes<E>(self, v: &[u8]) -> Result<Self::Value, E>where E: Error,

The input contains a byte array. The lifetime of the byte array is ephemeral and it may be destroyed after this method returns.

fn visit_borrowed_bytes<E>(self, v: &'de [u8]) -> Result<Self::Value, E>where E: Error,

The input contains a byte array that lives at least as long as the Deserializer.

fn visit_byte_buf<E>(self, v: Vec<u8, Global>) -> Result<Self::Value, E>where E: Error,

The input contains a byte array and ownership of the byte array is being given to the Visitor.

fn visit_none<E>(self) -> Result<Self::Value, E>where E: Error,

The input contains an optional that is absent.

fn visit_some<D>( self, deserializer: D ) -> Result<Self::Value, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

The input contains an optional that is present.

fn visit_unit<E>(self) -> Result<Self::Value, E>where E: Error,

The input contains a unit ().

fn visit_newtype_struct<D>( self, deserializer: D ) -> Result<Self::Value, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

The input contains a newtype struct.

fn visit_seq<A>( self, seq: A ) -> Result<Self::Value, <A as SeqAccess<'de>>::Error>where A: SeqAccess<'de>,

The input contains a sequence of elements.

fn visit_map<A>( self, map: A ) -> Result<Self::Value, <A as MapAccess<'de>>::Error>where A: MapAccess<'de>,

The input contains a key-value map.

fn visit_enum<A>( self, data: A ) -> Result<Self::Value, <A as EnumAccess<'de>>::Error>where A: EnumAccess<'de>,

The input contains an enum.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
