Struct rustc_span::ErrorGuaranteed

pub struct ErrorGuaranteed(pub(crate) ());

Useful type to use with Result<> indicate that an error has already been reported to the user, so no need to continue checking.

Implementations

impl ErrorGuaranteed

pub fn unchecked_claim_error_was_emitted() -> Self

👎Deprecated: Session::delay_span_bug should be preferred over this function

To be used only if you really know what you are doing… ideally, we would find a way to eliminate all calls to this method.

Trait Implementations

impl Clone for ErrorGuaranteed

fn clone(&self) -> ErrorGuaranteed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorGuaranteed

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for ErrorGuaranteed

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for ErrorGuaranteed

fn encode(&self, __encoder: &mut __E)

impl Hash for ErrorGuaranteed

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for ErrorGuaranteedwhere __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl Ord for ErrorGuaranteed

fn cmp(&self, other: &ErrorGuaranteed) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ErrorGuaranteed> for ErrorGuaranteed

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ErrorGuaranteed> for ErrorGuaranteed

fn partial_cmp(&self, other: &ErrorGuaranteed) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

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.
