Struct wasm_bindgen_backend::Diagnostic[−][src]

pub struct Diagnostic { /* fields omitted */ }

A struct representing a diagnostic to emit to the end-user as an error.

Implementations

impl Diagnostic[src]

pub fn error<T: Into<String>>(text: T) -> Diagnostic[src]

Generate a Diagnostic from an informational message with no Span

pub fn span_error<T: Into<String>>(span: Span, text: T) -> Diagnostic[src]

Generate a Diagnostic from a Span and an informational message

pub fn spanned_error<T: Into<String>>(
    node: &dyn ToTokens,
    text: T
) -> Diagnostic[src]

Generate a Diagnostic from the span of any tokenizable object and a message

pub fn from_vec(diagnostics: Vec<Diagnostic>) -> Result<(), Diagnostic>[src]

Attempt to generate a Diagnostic from a vector of other Diagnostic instances. If the Vec is empty, returns Ok(()), otherwise returns the new Diagnostic

pub fn panic(&self) -> ![src]

Immediately trigger a panic from this Diagnostic
