Trait Lock 

pub trait Lock<A: Zeroize + Bytes, PM: ProtectMode> {
    // Required method
    fn mlock(self) -> Result<Protected<A, PM, Locked>, Error>;
}

Available on crate feature protected only.

Protected region of memory that can be locked.

Required Methods

fn mlock(self) -> Result<Protected<A, PM, Locked>, Error>

Locks a region of memory, using mlock() on UNIX, or VirtualLock() on Windows. By default, the protect mode is set to ReadWrite (i.e., no exec) using mprotect() on UNIX, or VirtualProtect() on Windows. On Linux, it will also set MADV_DONTDUMP using madvise().

Errors

Returns error::Error::Io if the pages cannot be locked, for example because the process has reached its locked-memory limit.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
