Mojo struct 🡭

GtfView

@memory_only
struct GtfView[O: Origin[mut=O.mut]]

Zero-copy view over one GTF data line.

Lifetime: Valid only until the next parser read. Do not store; call .to_record() when the record must outlive the current iteration. Coordinates are 1-based inclusive.

Parameters

• O (Origin[mut=O.mut])

Fields

• start (UInt64)
• end (UInt64)
• score (Optional[Float64])
• strand (Optional[GtfStrand])
• phase (Optional[UInt8])

Implemented traits

AnyType, Deinitable, Movable
