Struct InlineCost 

pub struct InlineCost {
    pub body_size: u64,
    pub call_overhead: u64,
    pub estimated_savings: i64,
}

Cost model for inlining a single call site.

Fields

body_size: u64

Estimated code-size contribution of the callee body.

call_overhead: u64

Overhead of the call itself (stack frame, arg passing, return).

estimated_savings: i64

Estimated savings from inlining (e.g. eliminated argument allocations, constant propagation opportunities). May be negative.

Implementations

impl InlineCost

pub fn new() -> Self

Construct a zeroed cost estimate.

pub fn net_gain(&self) -> i64

Net gain from inlining: positive means inlining is beneficial.

pub fn is_profitable(&self) -> bool

Returns true when inlining is expected to be profitable.

Performs copy-assignment from source.

impl Debug for InlineCost

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for InlineCost

fn default() -> Self

Returns the “default value” for a type.
