Struct Message 

pub struct Message {
    pub span: Option<Range<usize>>,
    pub reason: Cow<'static, str>,
    pub rule_id: &'static str,
    pub source: &'static str,
}

A serializer or custom event producer diagnostic.

Static messages and identifiers require no allocation. A dynamically formatted reason can be supplied with String::into. Spans are half-open byte ranges in the source; consumers can derive line and column numbers when presenting them.

Fields

span: Option<Range<usize>>

Source bytes associated with this diagnostic, when available.

reason: Cow<'static, str>

Human-readable explanation.

rule_id: &'static str

Category of message.

source: &'static str

Namespace of message.
