collection-index

All codes

• Type: error
• Kind: usage (the caller misused the API)

What happened

Font::from_collection was asked for a member past the end of the font collection.

Why

Members are numbered from 0; a single font counts as a collection of one.

How to fix

Use an index below Font::collection_len(bytes).

Example

let font = Font::from_collection(ttc_bytes, 4)?; // the collection has 4 members (0..=3): collection-index

Data fields

• index: the member that was asked for.
• count: how many members the collection has.
