Expand description

Represents different types of validation errors that can occur when processing an M3U8 playlist.

This enum captures specific validation issues that may arise when checking the conformity of a playlist to the M3U8 specification. Each variant represents a distinct error, providing context for what went wrong during validation.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
