Constant MALLOCX_TCACHE_NONE

pub const MALLOCX_TCACHE_NONE: i32 = _; // 256i32

Do not use a thread-specific cache (tcache).

Unless MALLOCX_TCACHE(tc) or MALLOCX_TCACHE_NONE is specified, an automatically managed tcache will be used under many circumstances.

Safety

This option cannot be used in the same flags argument as MALLOCX_TCACHE(tc).
