Struct GcGenParams 

#[non_exhaustive]
pub struct GcGenParams {
    pub minor_multiplier: Option<c_int>,
    pub minor_to_major: Option<c_int>,
    pub major_to_minor: Option<c_int>,
}

Available on crate features lua55 or lua54 only.

Tuning parameters for the generational GC collector (Lua 5.4+).

More information can be found in the Lua documentation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

minor_multiplier: Option<c_int>

Frequency of minor (young-generation) collection steps.

minor_to_major: Option<c_int>

Threshold controlling how large the young generation can grow before triggering a shift from minor to major collection.

major_to_minor: Option<c_int>

Available on crate feature lua55 only.

Threshold controlling how much the major collection must shrink the heap before switching back to minor (young-generation) collection.
