Struct p8n_types::Table

pub struct Table<V: Hash + Debug + Clone + Eq, R: Clone + Copy + From<usize> + Into<usize>> { /* private fields */ }

Table mapping hashable values to and from numeric indices.

Implementations

impl<V: Hash + Debug + Clone + Eq, R: Clone + Copy + From<usize> + Into<usize>> Table<V, R>

pub fn with_capacity(cap: usize) -> Table<V, R>

Creates a new table with initial capacity cap.

pub fn insert(&mut self, v: &V) -> R

Inserts v into the table, returing its index. If v already exists in the table its not inserted again.

pub fn index(&self, s: &V) -> Result<R>

Returns the index of s in the table.

pub fn value<'a>(&'a self, i: R) -> Result<&'a V>

Returns the value of the entry with index i.

pub fn len(&self) -> usize

Number of entries in the table.

impl Table<Name, NameRef>

pub fn base_name(&self, idx: NameRef) -> Result<NameRef>

Shortcut for getting the index of the Name with the same base as idx but subscript None.

pub fn var<S: Into<Str>>(
    &mut self,
    name: S,
    subscript: Option<usize>,
    bits: usize
) -> Result<Variable>

Create a new variable with name and subscript, inserting the name if it’s not present in the table.

impl Table<Name, SegmentRef>

pub fn base_name(&self, idx: SegmentRef) -> Result<SegmentRef>

Shortcut for getting the index of the Segment with the same base as idx but subscript None.

Trait Implementations

impl<V: Clone + Hash + Debug + Clone + Eq, R: Clone + Clone + Copy + From<usize> + Into<usize>> Clone for Table<V, R>

fn clone(&self) -> Table<V, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug + Hash + Debug + Clone + Eq, R: Debug + Clone + Copy + From<usize> + Into<usize>> Debug for Table<V, R>

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

Formats the value using the given formatter.

impl<V: Hash + Debug + Clone + Eq, R: Clone + Copy + From<usize> + Into<usize>> Default for Table<V, R>

fn default() -> Table<V, R>

Returns the “default value” for a type.
