Struct SelectedDryIceReader 

Source 
pub struct SelectedDryIceReader<R, S = RawAsciiCodec, Q = RawQualityCodec, N = RawNameCodec, K = NoRecordKey, F = ReadAllFields> { /* private fields */ }
Expand description

Reader type returned when a field selection is specified on the builder.

This reader still advances through whole records in order, but it only prepares the fields implied by the selected field set. The selected field methods then live on SelectedRecord rather than on the reader itself.

Implementations§

Source§

impl<R, S, Q, N, K, F> SelectedDryIceReader<R, S, Q, N, K, F>
where R: Read, S: SequenceCodec, Q: QualityCodec, N: NameCodec, F: SelectionPlan,

Source

pub fn next_record( &mut self, ) -> Result<Option<SelectedRecord<'_, R, S, Q, N, K, F>>, DryIceError>

Advance to the next selected record in the file.

§Errors

Returns an error if the next block header or payload cannot be read or decoded, or if the on-disk codec tags do not match the reader’s configured codecs.
