Struct Diagnostics 

pub struct Diagnostics { /* private fields */ }

Diagnostics accumulated by one compilation.

Implementations

impl Diagnostics

pub fn new() -> Diagnostics

pub fn push(&mut self, d: Diagnostic)

pub fn extend(&mut self, other: Diagnostics)

pub fn has_errors(&self) -> bool

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn truncate(&mut self, mark: usize)

Drop everything reported after a mark taken with Diagnostics::len.

For a check run only to learn something — the checker infers a typed macro call’s arguments before the macro has decided what to do with them, and the real check of the expansion is the one whose diagnostics a reader should see. Truncation rather than a separate Diagnostics because it catches everything the run reported, including whatever pushed without going through the caller.

pub fn iter(&self) -> impl Iterator<Item = &Diagnostic>

pub fn sorted(&self) -> Vec<&Diagnostic>

Sorted by position, so a snapshot does not depend on the order checks happened to run in.

pub fn render(&self, map: &SourceMap) -> String
