Struct MRZParser 

pub struct MRZParser;

Top-level MRZ parser.

• try_parse returns Option<MRZResult> (None on error).
• parse returns Result<MRZResult, MRZError> (error when input is invalid or parsing fails).

Implementations

impl MRZParser

pub fn try_parse(input: Option<Vec<Option<String>>>) -> Option<MRZResult>

Attempt to parse the given MRZ lines, returning Some(MRZResult) on success or None if parsing fails for any reason.

Input accepts an optional outer vector whose elements may themselves be optional strings (to model upstream OCR results that may be null).

pub fn parse(input: Option<Vec<Option<String>>>) -> Result<MRZResult, MRZError>

Parse MRZ input and return a MRZResult or a MRZError.

High-level flow:

1. Polish input (filter nulls, uppercase, validate allowed MRZ chars).
2. Attempt to parse with the TD1 parser if it recognises the format.
3. Otherwise attempt TD2, then TD3.
4. If none match, return InvalidMRZInput.
