Struct ExecutionLimits 

pub struct ExecutionLimits {
    pub memory_bytes: usize,
    pub table_elements: usize,
    pub instances: usize,
    pub deadline_seconds: u64,
}

Fully-resolved execution limits for one session’s guests: the manifest’s capabilities.limits block with every omitted field replaced by its DEFAULT_*.

Fields

memory_bytes: usize

Cap on linear-memory growth, in bytes.

table_elements: usize

Cap on table growth, in elements.

instances: usize

Cap on instances a single store may create.

deadline_seconds: u64

Wall-clock budget for a single guest invocation, in seconds.

Implementations

impl ExecutionLimits

pub fn resolve(declared: Option<&ResourceLimits>) -> Self

Resolve a manifest capabilities.limits block, substituting the default for each field the manifest left out (and for the whole block when it is absent).

pub fn for_hook_calls(self, declared_deadline_seconds: Option<u64>) -> Self

This limit block re-flavored for hook lifecycle calls: every resource cap unchanged, but the wall-clock budget falls back to HOOK_DEFAULT_DEADLINE_SECONDS instead of DEFAULT_DEADLINE_SECONDS when the operator declared none.

Takes the undefaulted capabilities.limits.deadline_seconds rather than reading it back off self, because that is the only way to tell “the operator set nothing” from “the operator explicitly set 600” — the second must be honored verbatim, hooks included. Callers get it from crate::CapabilityPolicy::hook_limits.
