Struct writeable::Part

source ·
pub struct Part {
    pub category: &'static str,
    pub value: &'static str,
}
Expand description

Parts are used as annotations for formatted strings. For example, a string like Alice, Bob could assign a NAME part to the substrings Alice and Bob, and a PUNCTUATION part to , . This allows for example to apply styling only to names.

Part contains two fields, whose usage is left up to the producer of the Writeable. Conventionally, the category field will identify the formatting logic that produces the string/parts, whereas the value field will have semantic meaning. NAME and PUNCTUATION could thus be defined as

const NAME: Part = Part {
    category: "userlist",
    value: "name",
};
const PUNCTUATION: Part = Part {
    category: "userlist",
    value: "punctuation",
};

That said, consumers should not usually have to inspect Part internals. Instead, formatters should expose the Parts they produces as constants.

impl Part

source

pub const ERROR: Part = _

A part that should annotate error segments in TryWriteable output.

For an example, see TryWriteable.
