Struct SplitOff

pub struct SplitOff { /* private fields */ }

Mutates an existing vector by reducing its length to at and returns the new vector. Mimics Vec::split_off.

Only supports lists with statically sized elements.

Behavior

BEFORE: _ *list [at: u32]
AFTER:  _ *new_list

Preconditions

• the argument *list points to a properly BFieldCodec-encoded list
• all input arguments are properly BFieldCodec encoded

Postconditions

• *new_list points to a properly BFieldCodec-encoded list

Implementations

impl SplitOff

pub const OUT_OF_BOUNDS_ERROR_ID: i128 = 80i128

pub fn new(element_type: DataType) -> Self

Panics

Panics if the element has dynamic length, or if the static length is 0.

Trait Implementations

impl BasicSnippet for SplitOff

fn inputs(&self) -> Vec<(DataType, String)>

fn outputs(&self) -> Vec<(DataType, String)>

fn entrypoint(&self) -> String

fn code(&self, library: &mut Library) -> Vec<LabelledInstruction>

fn sign_offs(&self) -> HashMap<Reviewer, SignOffFingerprint>

Contains an entry for every sign off.

fn annotated_code(&self, library: &mut Library) -> Vec<LabelledInstruction>

fn link_for_isolated_run(&self) -> Vec<LabelledInstruction>

fn init_stack_for_isolated_run(&self) -> Vec<BFieldElement>

Initial stack on program start, when the snippet runs in isolation.

fn stack_diff(&self) -> isize

impl Clone for SplitOff

fn clone(&self) -> SplitOff

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SplitOff

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

Formats the value using the given formatter.

impl Hash for SplitOff

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

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 SplitOff

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