Struct StackLimits

pub struct StackLimits {
    pub initial_value_stack_height: usize,
    pub maximum_value_stack_height: usize,
    pub maximum_recursion_depth: usize,
}

The configured limits of the Wasm stack.

Fields

initial_value_stack_height: usize

The initial value stack height that the Wasm stack prepares.

maximum_value_stack_height: usize

The maximum value stack height in use that the Wasm stack allows.

maximum_recursion_depth: usize

The maximum number of nested calls that the Wasm stack allows.

Implementations

impl StackLimits

pub fn new( initial_value_stack_height: usize, maximum_value_stack_height: usize, maximum_recursion_depth: usize, ) -> Result<Self, LimitsError>

Creates a new StackLimits configuration.

Errors

If the initial_value_stack_height exceeds maximum_value_stack_height.
