Struct JsSnapshotLimits 

pub struct JsSnapshotLimits { /* private fields */ }

Available on crate features js and std only.

Resource limits applied while copying values out of the JavaScript engine.

These limits cover evaluation results, function results, thrown values, and arguments passed from JavaScript into host functions. They bound the Rust-side work performed after (or during) script execution, which is separate from the JavaScript runtime’s loop, recursion, and stack limits.

Implementations

impl JsSnapshotLimits
