Struct Diagnostic 

#[non_exhaustive]
pub struct Diagnostic {
    pub severity: Severity,
    pub message: String,
    pub range: (u32, u32, u32, u32),
    pub code: Option<String>,
    pub source: Option<String>,
}

A single diagnostic finding.

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.

severity: Severity

Severity ladder.

message: String

Human-readable message.

range: (u32, u32, u32, u32)

Zero-based (start_line, start_char, end_line, end_char) range.

code: Option<String>

Optional diagnostic code (e.g. lint rule name).

source: Option<String>

Optional source identifier (e.g. linter name).

Implementations

impl Diagnostic

pub fn new( severity: Severity, message: impl Into<String>, range: (u32, u32, u32, u32), ) -> Self

Construct a diagnostic with required fields. Optional fields default to None.

pub fn with_code(self, code: impl Into<String>) -> Self

Attach a diagnostic code.

pub fn with_source(self, source: impl Into<String>) -> Self

Attach a source identifier.

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

Performs copy-assignment from source.
