Struct DiagnosticCode 

pub struct DiagnosticCode<D = DefaultDiscriminant> {
    pub discriminant: D,
    /* private fields */
}

A code that identifies a given kind of diagnostic.

These are meant to be used by users as unchanging identifiers by which they can look up more detailed information about the diagnostic.

Fields

discriminant: D

The numeric discriminant.

Implementations

impl<D> DiagnosticCode<D>

pub fn new(prefix: [u8; 3], discriminant: D) -> Result<Self, Utf8Error>

Constructs a new DiagnosticCode.

Errors

If prefix is not valid UTF-8, an error variant will be returned.

See Also

• new_unchecked

pub const unsafe fn new_unchecked(prefix: [u8; 3], discriminant: D) -> Self

Constructs a new DiagnosticCode.

Safety

The caller is responsible for ensuring prefix is valid UTF-8. For a safe alternative, see new.

See Also

• new

pub const fn prefix_bytes(&self) -> &[u8; 3]

Gets this code’s prefix as a slice of raw, UTF-8-encoded bytes.

See Also

• prefix_str

pub const fn prefix_str(&self) -> &str

Gets this code’s prefix as a string slice.

Trait Implementations

impl<D: Clone> Clone for DiagnosticCode<D>

fn clone(&self) -> DiagnosticCode<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for DiagnosticCode<D>

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

Formats the value using the given formatter.

impl<D> Display for DiagnosticCode<D>

where D: Discriminant,

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

Formats the value using the given formatter.

impl<D: Hash> Hash for DiagnosticCode<D>

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<D: Ord> Ord for DiagnosticCode<D>

fn cmp(&self, other: &DiagnosticCode<D>) -> 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<D: PartialEq> PartialEq for DiagnosticCode<D>

fn eq(&self, other: &DiagnosticCode<D>) -> 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<D: PartialOrd> PartialOrd for DiagnosticCode<D>

fn partial_cmp(&self, other: &DiagnosticCode<D>) -> 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.
