Enum CacheControl

#[non_exhaustive]
pub enum CacheControl {
    Never,
    Expires {
        expiration: OffsetDateTime,
    },
    Session,
    Unknown,
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Never

Do not cache this result.

Expires

Cache this result and use it for subsequent requests in the current Cargo invocation until the specified time.

Fields

expiration: OffsetDateTime

Session

Cache this result and use it for all subsequent requests in the current Cargo invocation.

Unknown

Trait Implementations

impl Clone for CacheControl

fn clone(&self) -> CacheControl

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheControl

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CacheControl

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheControl

fn eq(&self, other: &CacheControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CacheControl

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CacheControl

impl StructuralPartialEq for CacheControl

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.
