Struct MatrixBuilder 

pub struct MatrixBuilder { /* private fields */ }

Builder for creating expression matrices from SOFT data

Implementations

impl MatrixBuilder

pub fn new() -> Self

Create a new matrix builder with default configuration

pub fn with_config(config: MatrixConfig) -> Self

Create a new matrix builder with custom configuration

pub fn from_soft<R>(&self, reader: SoftReader<R>) -> Result<ExpressionMatrix>

where R: BufRead,

Build expression matrix from a SOFT file reader

Uses a single-pass over the reader via next_record(), collecting both GSM samples and the GPL platform in one sweep.

Errors

Returns an error if:

• The SOFT data cannot be parsed
• No samples with data tables are found
• Required columns (ID_REF, VALUE) are missing
• Arrow data construction fails

pub fn build_all<R>( &self, reader: SoftReader<R>, ) -> Result<(ExpressionMatrix, SampleMetadata, Option<PlatformAnnotation>)>

where R: BufRead,

Build expression matrix, sample metadata, and platform annotation in a single pass over the SOFT reader.

Returns a tuple of (ExpressionMatrix, SampleMetadata, Option<PlatformAnnotation>).

Errors

Returns an error if:

• The SOFT data cannot be parsed
• No samples with data tables are found
• Required columns (ID_REF, VALUE) are missing
• Arrow data construction fails
