Enum DiagnosticCategory 

pub enum DiagnosticCategory {
    Syntax,
    Semantic,
    Layout,
    Text,
    Pdf,
    Io,
    Internal,
}

What kind of thing a diagnostic describes.

Category is metadata, never identity. The catalog groups by this so a rule can change phase (parser → evaluator, fonts → text shaping) without breaking its stable DiagnosticCode.

Examples

use mos_core::{DiagnosticCategory, codes};

assert_eq!(codes::MOS0033.category(), DiagnosticCategory::Semantic);

Variants

Syntax

Surface syntax: tokenisation, directive shape, inline grammar.

Semantic

Semantic lowering: name resolution, schema validation, references.

Layout

Page geometry, paper sizes, style application.

Text

Text shaping, glyph coverage, font selection.

Pdf

PDF backend emission and packaging.

Io

Filesystem and asset I/O (read failure, decode failure, …).

Internal

Compiler-internal invariants (should never reach end users).

Trait Implementations

impl Clone for DiagnosticCategory

fn clone(&self) -> DiagnosticCategory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticCategory

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

Formats the value using the given formatter.

impl Display for DiagnosticCategory

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

Formats the value using the given formatter.

impl Hash for DiagnosticCategory

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 DiagnosticCategory

fn cmp(&self, other: &DiagnosticCategory) -> 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 DiagnosticCategory

fn eq(&self, other: &DiagnosticCategory) -> 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 DiagnosticCategory

fn partial_cmp(&self, other: &DiagnosticCategory) -> 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.
