Struct TwoDa 

pub struct TwoDa {
    pub headers: Vec<String>,
    pub rows: Vec<TwoDaRow>,
}

In-memory representation of a binary 2DA table.

The structure keeps header order and row order stable so a write->read roundtrip remains deterministic.

Fields

headers: Vec<String>

Ordered column headers.

rows: Vec<TwoDaRow>

Ordered table rows.

Implementations

impl TwoDa

pub fn empty() -> Self

Creates an empty table with no headers and no rows.

pub fn new(headers: Vec<String>) -> Self

Creates an empty table with the provided headers.

pub fn push_row( &mut self, label: impl Into<String>, cells: Vec<String>, ) -> Result<(), TwoDaBinaryError>

Appends a row, validating that cell count matches header count.

Errors

TwoDaBinaryError::InvalidTable when cells is not as wide as the header list, naming both widths. Nothing is appended in that case. The cell contents are not checked here; a NUL or a tab inside one is refused later, by the writer.

pub fn row_count(&self) -> usize

Returns the number of rows.

pub fn column_count(&self) -> usize

Returns the number of columns.

pub fn cell(&self, row_index: usize, column_name: &str) -> Option<&str>

Returns a cell by row index and column header name.

Trait Implementations

impl Clone for TwoDa

fn clone(&self) -> TwoDa

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TwoDa

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DecodeBinary for TwoDa

type Error = TwoDaBinaryError

Error type used by the format.

fn decode_binary(bytes: &[u8]) -> Result<Self, Self::Error>

Decodes a value from raw bytes.

impl EncodeBinary for TwoDa

type Error = TwoDaBinaryError

Error type used by the format.

fn encode_binary(&self) -> Result<Vec<u8>, Self::Error>

Encodes a value into an owned byte buffer.

impl PartialEq for TwoDa

fn eq(&self, other: &TwoDa) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
