[−][src]Struct lucet_runtime::Limits

#[repr(C)]
pub struct Limits {
    pub heap_memory_size: usize,
    pub heap_address_space_size: usize,
    pub stack_size: usize,
    pub globals_size: usize,
}

Runtime limits for the various memories that back a Lucet instance.

Each value is specified in bytes, and must be evenly divisible by the host page size (4K).

Fields

heap_memory_size: usize

Max size of the heap, which can be backed by real memory. (default 1M)

heap_address_space_size: usize

Size of total virtual memory. (default 8G)

stack_size: usize

Size of the guest stack. (default 128K)

globals_size: usize

Size of the globals region in bytes; each global uses 8 bytes. (default 4K)

Methods

impl Limits[src]

pub fn total_memory_size(&self) -> usize[src]

pub fn validate(&self) -> Result<(), Error>[src]

Validate that the limits are aligned to page sizes, and that the stack is not empty.
