Struct Stack

pub struct Stack {
    pub values: Vec<Value>,
}
Expand description

§The operand stack

StackAssembly’s evaluation model is based on an implicit stack which stores all operands.

Aside from this, the stack is an important communication channel between script and host. Please refer to Eval’s stack field for more information on that.

Fields§

§values: Vec<Value>

§The values on the stack

Implementations§

Source§

impl Stack

Source

pub fn push(&mut self, value: impl Into<Value>)

§Push a value to top of the stack
Source

pub fn pop(&mut self) -> Result<Value, StackUnderflow>

§Pop a value from the top of the stack

Return StackUnderflow, if no value is available on the stack, which provides an automatic conversion to Effect.

Source

pub fn to_i32_slice(&self) -> &[i32]

§Access the stack as a slice of i32 values
Source

pub fn to_u32_slice(&self) -> &[u32]

§Access the stack as a slice of u32 values
