pub enum DiagnosticMessage {
Str(String),
FluentIdentifier(Cow<'static, str>, Option<Cow<'static, str>>),
}
Expand description
Abstraction over a message in a diagnostic to support both translatable and non-translatable diagnostic messages.
Intended to be removed once diagnostics are entirely translatable.
Variants
Str(String)
Non-translatable diagnostic message.
FluentIdentifier(Cow<'static, str>, Option<Cow<'static, str>>)
Identifier for a Fluent message (with optional attribute) corresponding to the diagnostic message.

Implementations
sourceimpl DiagnosticMessage
impl DiagnosticMessage
sourcepub fn with_subdiagnostic_message(&self, sub: SubdiagnosticMessage) -> Self
pub fn with_subdiagnostic_message(&self, sub: SubdiagnosticMessage) -> Self
Given a SubdiagnosticMessage
which may contain a Fluent attribute, create a new
DiagnosticMessage
that combines that attribute with the Fluent identifier of self
.
- If the
SubdiagnosticMessage
is non-translatable then return the message as aDiagnosticMessage
. - If
self
is non-translatable then returnself
’s message.
sourcepub fn expect_str(&self) -> &str
pub fn expect_str(&self) -> &str
Returns the String
contained within the DiagnosticMessage::Str
variant, assuming that
this diagnostic message is of the legacy, non-translatable variety. Panics if this
assumption does not hold.
Don’t use this - it exists to support some places that do comparison with diagnostic strings.

Translating into a subdiagnostic message from a diagnostic message is a little strange - but
the subdiagnostic functions (e.g. span_label
) take a SubdiagnosticMessage
and the
subdiagnostic derive refers to typed identifiers that are DiagnosticMessage
s, so need to be
able to convert between these, as much as they’ll be converted back into DiagnosticMessage
using with_subdiagnostic_message
eventually. Don’t use this other than for the derive.
