Struct ProfConfig 

#[non_exhaustive]
pub struct ProfConfig {
    pub mode: ProfConfigMode,
    pub sample_interval: Option<usize>,
    pub max_profiler_bytes: Option<usize>,
    pub seed: Option<u64>,
    pub accum: bool,
    pub max_stack_depth: Option<usize>,
    pub dump_at_exit: Option<PathBuf>,
    pub dump_format: DumpFormat,
}

Ergonomic, Rust-facing sibling of mi_prof_config_t (include/mimalloc/profile.h) for enable_heap_profiling_with.

Fields mirror the C struct one-for-one, but trade its 0/NULL-means-unset raw-integer conventions for Option<T> and enums where that reads better. #[non_exhaustive] + Default keeps future fields additive: build from Default::default() and set the fields you need, e.g.

use mimalloc_pprof::ProfConfig;
let mut config = ProfConfig::default();
config.sample_interval = Some(4096);

(Within this crate, struct-update syntax like ProfConfig { sample_interval: Some(4096), ..Default::default() } also works; #[non_exhaustive] only blocks struct-literal construction from other crates, so new fields stay non-breaking for them.)

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.

mode: ProfConfigMode

See ProfConfigMode.

sample_interval: Option<usize>

Average bytes between samples. None = env/default (512 KiB).

max_profiler_bytes: Option<usize>

Budget (bytes) for profiler-internal persistent sampling state (sample records, the stack intern table, interned stack entries). None = unbudgeted (cap-bounded only).

seed: Option<u64>

None = nondeterministic.

accum: bool

max_stack_depth: Option<usize>

None = default (32); compile cap 128.

dump_at_exit: Option<PathBuf>

Path to dump the profile to at process exit. None = no exit dump.

dump_format: DumpFormat

Format used for the exit dump. Ignored if dump_at_exit is None.
