[][src]Struct rustc_errors::diagnostic_builder::DiagnosticBuilder

#[must_use]
pub struct DiagnosticBuilder<'a>(Box<DiagnosticBuilderInner<'a>>);
⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Used for emitting structured error messages and other diagnostic information.

If there is some state in a downstream crate you would like to access in the methods of DiagnosticBuilder here, consider extending HandlerFlags, accessed via self.handler.flags.

Methods

impl<'a> DiagnosticBuilder<'a>[src]

pub fn emit(&mut self)[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Emit the diagnostic.

pub fn emit_unless(&mut self, delay: bool)[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Emit the diagnostic unless delay is true, in which case the emission will be delayed as a bug.

See emit and delay_as_bug for details.

pub fn stash(self, span: Span, key: StashKey)[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Stashes diagnostic for possible later improvement in a different, later stage of the compiler. The diagnostic can be accessed with the provided span and key through .steal_diagnostic on Handler.

As with buffer, this is unless the handler has disabled such buffering.

pub fn into_diagnostic(self) -> Option<(Diagnostic, &'a Handler)>[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Converts the builder to a Diagnostic for later emission, unless handler has disabled such buffering.

pub fn buffer(self, buffered_diagnostics: &mut Vec<Diagnostic>)[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Buffers the diagnostic for later emission, unless handler has disabled such buffering.

pub fn sub<S: Into<MultiSpan>>(
    &mut self,
    level: Level,
    message: &str,
    span: Option<S>
) -> &mut Self
[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Convenience function for internal use, clients should use one of the span_* methods instead.

pub fn delay_as_bug(&mut self)[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Delay emission of this diagnostic as a bug.

This can be useful in contexts where an error indicates a bug but typically this only happens when other compilation errors have already happened. In those cases this can be used to defer emission of this diagnostic as a bug in the compiler only if no other errors have been emitted.

In the meantime, though, callsites are required to deal with the "bug" locally in whichever way makes the most sense.

pub fn span_label<T: Into<String>>(&mut self, span: Span, label: T) -> &mut Self[src]

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Adds a span/label to be included in the resulting snippet. This is pushed onto the MultiSpan that was created when the diagnostic was first built. If you don't call this function at all, and you just supplied a Span to create the diagnostic, then the snippet will just include that Span, which is called the primary span.

In case of short messages and a simple suggestion, rustc displays it as a label:

try adding parentheses: `(tup.0).1`

The message

  • should not end in any punctuation (a : is added automatically)
  • should not be a question (avoid language like "did you mean")
  • should not contain any phrases like "the following", "as shown", etc.
  • may look like "to do xyz, use" or "to do xyz, use abc"
  • may contain a name of a function, variable, or type, but not whole expressions
