Runtime context description.

Variants

Predicate

Fields

program: RuntimePredicate

Predicate program to be executed

Current context is a predicate verification.

Script

Fields

block_height: u32

Block height of the context

Current context is a script execution.

Call

Fields

block_height: u32

Block height of the context

Current context is under a CALL scope

NotInitialized

No transaction initialized/invalid context.

Implementations

impl Context

pub const fn is_predicate(&self) -> bool

Check if the context is predicate

pub const fn is_external(&self) -> bool

Return true if the context is external; false otherwise.

pub const fn predicate(&self) -> Option<&RuntimePredicate>

Return the program to be executed, if its a predicate

pub const fn block_height(&self) -> Option<u32>

Return the block height from the context, if either script or call

pub fn update_from_frame_pointer(&mut self, fp: Word)

Update the context according to the provided frame pointer

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Context

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<Context> for Context

fn eq(&self, other: &Context) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Context

impl StructuralEq for Context
