Struct JumpTableData 

pub struct JumpTableData { /* private fields */ }

Contents of a jump table.

All jump tables use 0-based indexing and are densely populated.

The default block for the jump table is stored as the first element of the underlying vector. It can be accessed through the default_block and default_block_mut functions. All blocks may be iterated using the all_branches and all_branches_mut functions, which will both iterate over the default block first.

Implementations

impl JumpTableData

pub fn new(def: BlockCall, table: &[BlockCall]) -> JumpTableData

Create a new jump table with the provided blocks.

pub fn default_block(&self) -> BlockCall

Fetch the default block for this jump table.

pub fn default_block_mut(&mut self) -> &mut BlockCall

Mutable access to the default block of this jump table.

pub fn all_branches(&self) -> &[BlockCall]

The jump table and default block as a single slice. The default block will always be first.

pub fn all_branches_mut(&mut self) -> &mut [BlockCall]

The jump table and default block as a single mutable slice. The default block will always be first.

pub fn as_slice(&self) -> &[BlockCall]

Access the jump table as a slice. This excludes the default block.

pub fn as_mut_slice(&mut self) -> &mut [BlockCall]

Access the jump table as a mutable slice. This excludes the default block.

pub fn iter(&self) -> Iter<'_, BlockCall>

👎Deprecated since 7.0.0: please use .as_slice() instead

Returns an iterator to the jump table, excluding the default block.

pub fn iter_mut(&mut self) -> IterMut<'_, BlockCall>

👎Deprecated since 7.0.0: please use .as_mut_slice() instead

Returns an iterator that allows modifying each value, excluding the default block.

pub fn clear(&mut self)

Clears all entries in this jump table, except for the default block.

pub fn display<'a>(&'a self, pool: &'a ListPool<Value>) -> DisplayJumpTable<'a>

Return a value that can display the contents of this jump table.

Trait Implementations

impl Clone for JumpTableData

fn clone(&self) -> JumpTableData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JumpTableData

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

Formats the value using the given formatter.

impl Hash for JumpTableData

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for JumpTableData

fn eq(&self, other: &JumpTableData) -> 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.
