Struct ErrorGuaranteed

pub struct ErrorGuaranteed(/* private fields */);

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 const fn new_unchecked() -> Self

Creates a new ErrorGuaranteed.

Use of this method is discouraged.

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 EmissionGuarantee for ErrorGuaranteed

type EmitResult = ErrorGuaranteed

This exists so that bugs and fatal errors can both result in ! (an abort) when emitted, but have different aborting behaviour.

fn emit_producing_guarantee( db: &mut DiagnosticBuilder<'_, Self>, ) -> Self::EmitResult

Implementation of DiagnosticBuilder::emit, fully controlled by each impl of EmissionGuarantee, to make it impossible to create a value of Self::EmitResult without actually performing the emission.

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 Ord for ErrorGuaranteed

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ErrorGuaranteed

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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