pub enum SubdiagnosticMessage {
Str(String),
FluentIdentifier(Cow<'static, str>),
FluentAttr(Cow<'static, str>),
}
Expand description
Abstraction over a message in a subdiagnostic (i.e. label, note, help, etc) to support both translatable and non-translatable diagnostic messages.
Translatable messages for subdiagnostics are typically attributes attached to a larger Fluent
message so messages of this type must be combined with a DiagnosticMessage
(using
DiagnosticMessage::with_subdiagnostic_message
) before rendering. However, subdiagnostics from
the SessionSubdiagnostic
derive refer to Fluent identifiers directly.
Variants
Str(String)
Non-translatable diagnostic message.
FluentIdentifier(Cow<'static, str>)
Identifier of a Fluent message. Instances of this variant are generated by the
SessionSubdiagnostic
derive.
FluentAttr(Cow<'static, str>)
Attribute of a Fluent message. Needs to be combined with a Fluent identifier to produce an
actual translated message. Instances of this variant are generated by the fluent_messages
macro.
Trait Implementations
sourceimpl<S: Into<String>> From<S> for SubdiagnosticMessage
impl<S: Into<String>> From<S> for SubdiagnosticMessage
From
impl that enables existing diagnostic calls to functions which now take
impl Into<SubdiagnosticMessage>
to continue to work as before.
sourceimpl Into<SubdiagnosticMessage> for DiagnosticMessage
impl Into<SubdiagnosticMessage> for DiagnosticMessage
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.
