Struct ClosureLayout 

Source
pub struct ClosureLayout {
    pub fn_ptr_offset: usize,

Expand description

Detailed layout information for a closure.

Fields§

§fn_ptr_offset: usize

Byte offset of the function pointer from closure start.

§env_offset: usize

Byte offset of the captured environment from closure start.

§env_size: usize

Total size of the captured environment in bytes.

§arity: usize

Number of parameters the function takes (total arity).

§num_captured: usize

Number of captured variables.

§object_layout: ObjectLayout

The overall object layout.

Implementations§

Source§
