pub enum GraphemeIncomplete {
    PreContext(usize),
    PrevChunk,
    NextChunk,
    InvalidOffset,
}
Expand description

An error return indicating that not enough content was available in the provided chunk to satisfy the query, and that more content must be provided.

Variants

PreContext(usize)

More pre-context is needed. The caller should call provide_context with a chunk ending at the offset given, then retry the query. This will only be returned if the chunk_start parameter is nonzero.

PrevChunk

When requesting prev_boundary, the cursor is moving past the beginning of the current chunk, so the chunk before that is requested. This will only be returned if the chunk_start parameter is nonzero.

NextChunk

When requesting next_boundary, the cursor is moving past the end of the current chunk, so the chunk after that is requested. This will only be returned if the chunk ends before the len parameter provided on creation of the cursor.

InvalidOffset

An error returned when the chunk given does not contain the cursor position.
