Struct KeyTable 

pub struct KeyTable { /* private fields */ }

The sorted table.

Implementations

impl KeyTable

pub fn new(pairs: Vec<(u64, u32)>) -> Self

Builds the table from (key, ordinal) pairs, in any order.

pub fn get(&self, key: u64) -> Option<u32>

The ordinal stored under key.

pub fn len(&self) -> usize

The entry count.

pub fn is_empty(&self) -> bool

Whether the table is empty.

pub fn write_to(&self, out: &mut impl Write) -> Result<(), KeyTableError>

Writes the layout.

Errors

Returns KeyTableError::Io when writing fails.

pub fn read_from(input: &mut impl Read) -> Result<Self, KeyTableError>

Reads the layout.

Errors

Returns KeyTableError for a truncated or foreign table.
