Implementations

impl Diagnostic

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

Creates a new diagnostic with the given level and message.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Return the children diagnostics of self.

pub fn level(&self) -> Level

Return the level of self.

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.

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.

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.

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.
