ExpressionContext

interface ExpressionContext(source)

The context used while converting a high-level Expression to a low-level CompiledExpression.

It defines how to resolve certain expressions (TextUnit, bitmaps) to their MapLibre counterparts. MapLibre Compose users should not need to implement this interface; it is used internally by the MapLibre Compose library.
