Function: parsePatternCached()

parsePatternCached(value): Pattern | null

Defined in: packages/core/src/pattern/parser.ts:134

Parses a pattern(...) paint string via parsePattern, memoizing the result in a bounded LRU cache shared by every rendering backend.

Backends should prefer this over parsePattern on any render path, where the same paint string resolves for every element on every frame.

The returned object is shared between callers and must not be mutated; parse it yourself with parsePattern when a private, mutable copy is required.

Parameters

Parameter	Type	Description
value	string	The paint string to parse, e.g. pattern(diagonal, #1a6, #fff0, 8).

Returns

Pattern | null

The parsed pattern, or null when the string is not a valid pattern.
