Struct Table 

pub struct Table { /* private fields */ }

A table: its columns and the rows of every fragment.

Implementations

impl Table

pub fn name(&self) -> &str

Returns the table name.

pub fn rows(&self) -> impl Iterator<Item = Row<'_>>

Returns the rows of the table, in order.

pub fn rows_in_key_order(&self, column: &str) -> Result<Vec<Row<'_>>>

Returns the rows of the table in the order of the game’s key lookup table, given the key column.

The game indexes each table by key in an open addressing table with one slot per row (13 if empty): a row goes to the slot key_hash modulo the row count gives, or the next free one. Code iterating that index visits the rows in slot order.

Errors

Returns an error if the table has no such column.

pub fn rows_in_key_order_by( &self, key: impl Fn(&Row<'_>) -> Result<String>, ) -> Result<Vec<Row<'_>>>

Returns the rows of the table in the order of the game’s key lookup table, given each row’s key (tables with several key columns join their values, as in province + region). See Self::rows_in_key_order.

Errors

Returns an error if the key of a row can’t be built.

pub fn len(&self) -> usize

Returns the number of rows.

pub fn is_empty(&self) -> bool

Returns if the table has no rows.

pub fn column_names(&self) -> impl Iterator<Item = &str>

Returns the names of the columns, in no particular order.

pub fn column(&self, column: &str) -> Result<usize>

Returns the position of a column.

Errors

Returns an error if the table has no such column.
