Enum TextSegment 

pub enum TextSegment {
    Literal(String),
    Expr(Arc<Expr>),
    MarkupOpen {
        name: String,
        properties: Vec<(String, String)>,
    },
    MarkupClose {
        name: String,
    },
    MarkupSelfClose {
        name: String,
        properties: Vec<(String, String)>,
    },
}

One segment of text that may contain {expr} fragments or inline markup.

Line text, option text, line-variant text, and command argument strings are all stored as Vec<TextSegment> so that {expr} fragments are parsed once at compile time and evaluated cheaply at runtime. Markup open/close/self-close segments record tag boundaries without carrying any text; byte offsets into the final rendered string are computed at runtime by crate::runtime.

Variants

Literal(String)

A literal string with no interpolation.

Expr(Arc<Expr>)

An {expr} fragment whose source has already been parsed.

MarkupOpen

An opening markup tag: [name] or [name key=val …].

Fields

name: String

Tag name, e.g. wave in [wave].

properties: Vec<(String, String)>

Zero or more key=value pairs.

MarkupClose

A closing markup tag: [/name].

Fields

name: String

Tag name matched against the most recent open, e.g. wave in [/wave].

MarkupSelfClose

A self-closing markup tag: [name /] or [name key=val … /].

Fields

name: String

Tag name, e.g. pause in [pause /].

properties: Vec<(String, String)>

Zero or more key=value pairs.
