Struct DiagSign 

#[non_exhaustive]
pub struct DiagSign {
    pub row: usize,
    pub ch: char,
    pub priority: u8,
}

A single diagnostic sign emitted from the syntax pipeline.

Carries only renderer-agnostic fields: row, ch, and priority. The TUI adapter converts these to ratatui-styled hjkl_buffer::Sign objects using its own colour choices.

Examples

use hjkl_syntax::DiagSign;
let s = DiagSign::new(3, 'E', 100);
assert_eq!(s.row, 3);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

row: usize

Document row (0-indexed).

ch: char

Gutter character (e.g. 'E' for a syntax error).

priority: u8

Gutter priority — higher wins when multiple signs land on the same row.

Implementations

impl DiagSign

pub fn new(row: usize, ch: char, priority: u8) -> Self

Create a new diagnostic sign.

Examples

use hjkl_syntax::DiagSign;
let s = DiagSign::new(1, 'E', 100);
assert_eq!(s.row, 1);
assert_eq!(s.ch, 'E');
assert_eq!(s.priority, 100);

Trait Implementations

impl Clone for DiagSign

fn clone(&self) -> DiagSign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagSign

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

Formats the value using the given formatter.

impl Default for DiagSign

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DiagSign

fn eq(&self, other: &DiagSign) -> 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.
