Matrix

Struct Matrix 

Source
pub struct Matrix { /* private fields */ }
Expand description

The recorded facts of one or more matrix files, and the lookup the gate performs.

Implementations§

Source§

impl Matrix

Source

pub fn new() -> Self

An empty matrix: everything is off.

Source

pub fn parse(text: &str) -> Result<Matrix, ParseError>

Read one tab-separated file. The first non-comment line is the header; columns are matched by name, so order does not matter and unknown columns are kept in Row::extra. Blank lines and lines starting with # are skipped.

Source

pub fn from_rows(rows: Vec<Row>) -> Matrix

A matrix of exactly these rows (what a conformance run produces).

Source

pub fn merge(&mut self, other: Matrix)

Add the rows of another file. A reader merges files; nothing is deduplicated.

Source

pub fn rows(&self) -> &[Row]

The rows, in file order.

Source

pub fn to_tsv(&self) -> String

Write the known columns, then the sorted union of unknown columns. Round-trips what Matrix::parse read, apart from comments, blank lines and column order.

Source

pub fn lookup( &self, subject: &CapabilityId, backend: &str, version: &str, actual: &Config, ) -> Lookup

The gate’s lookup. Rows match on subject, backend and version exactly, and on config when every fact the row names is also in actual. Off wins: one matching no makes the answer off even if another matching row says yes.

Source

pub fn enabled( &self, subject: &CapabilityId, backend: &str, version: &str, actual: &Config, ) -> bool

Whether the capability is on. Anything but Lookup::On is false.
