Struct StyleMeta 

pub struct StyleMeta {
    pub link: Option<Arc<str>>,
    pub link_id: Option<Arc<str>>,
    pub meta: Option<Arc<BTreeMap<String, MetaValue>>>,
}

Metadata for styles, used for hyperlinks and custom data.

This is kept separate from Style to preserve Style: Copy for the common case. Only segments with links or metadata need a StyleMeta.

Uses BTreeMap instead of HashMap for deterministic ordering, which is important for segment simplification and serialization.

Fields

link: Option<Arc<str>>

Hyperlink URL (terminal OSC 8 escape sequence).

link_id: Option<Arc<str>>

Link ID for grouping multiple segments with the same link.

meta: Option<Arc<BTreeMap<String, MetaValue>>>

Custom metadata (used by Textual for event handlers).

Implementations

impl StyleMeta

pub fn new() -> Self

pub fn is_empty(&self) -> bool

Check if this meta has any content.

pub fn combine(&self, other: &StyleMeta) -> Self

Combine with another StyleMeta, with other taking precedence.
