Implementations§

Source §

impl Diagnostic

Source

pub fn new<T: Into<String>>(level: Level, message: T) -> Diagnostic

Creates a new diagnostic with the given level and message.

Source

pub fn spanned<S, T>(spans: S, level: Level, message: T) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Creates a new diagnostic with the given level and message pointing to the given set of spans.

Source

pub fn spanned_child<S, T>( self, spans: S, level: Level, message: T, ) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Adds a new child diagnostic message to self with the level and the given spans and message.

Source

pub fn child<T: Into<String>>(self, level: Level, message: T) -> Diagnostic

Adds a new child diagnostic message to self with level and the given message.

Source

pub fn span_error<S, T>(self, spans: S, message: T) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Adds a new child diagnostic message to self with the level identified by this method’s name with the given spans and message.

Source

pub fn error<T: Into<String>>(self, message: T) -> Diagnostic

Adds a new child diagnostic message to self with the level identified by this method’s name with the given message.

Source

pub fn span_warning<S, T>(self, spans: S, message: T) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Adds a new child diagnostic message to self with the level identified by this method’s name with the given spans and message.

Source

pub fn warning<T: Into<String>>(self, message: T) -> Diagnostic

Adds a new child diagnostic message to self with the level identified by this method’s name with the given message.

Source

pub fn span_note<S, T>(self, spans: S, message: T) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Adds a new child diagnostic message to self with the level identified by this method’s name with the given spans and message.

Source

pub fn note<T: Into<String>>(self, message: T) -> Diagnostic

Adds a new child diagnostic message to self with the level identified by this method’s name with the given message.

Source

pub fn span_help<S, T>(self, spans: S, message: T) -> Diagnostic
where S: MultiSpan, T: Into<String>,

Adds a new child diagnostic message to self with the level identified by this method’s name with the given spans and message.

Source

pub fn help<T: Into<String>>(self, message: T) -> Diagnostic

Adds a new child diagnostic message to self with the level identified by this method’s name with the given message.

Source

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

Return the children diagnostics of self.

Source

pub fn level(&self) -> Level

Return the level of self.

Source

pub fn emit_as_item_tokens(self) -> TokenStream

Emit tokens, suitable for item contexts, to generate a comple-time diagnostic corresponding to self. On nightly, this directly emits the error and returns an empty token stream.

Source

pub fn emit_as_item_tokens_or(self, default: TokenStream) -> TokenStream

Emit tokens, suitable for item contexts, to generate a comple-time diagnostic corresponding to self. On nightly, this directly emits the error and returns default.

Source

pub fn emit_as_expr_tokens(self) -> TokenStream

Emit tokens, suitable for expression contexts, to generate a comple-time diagnostic corresponding to self. On nightly, this directly emits the error and returns a () token stream.

Source

pub fn emit_as_expr_tokens_or(self, default: TokenStream) -> TokenStream

Emit tokens, suitable for expressioon contexts, to generate a comple-time diagnostic corresponding to self. On nightly, this directly emits the error and returns default.
