Required Methods§

Source

fn access_mode(&mut self, access: u32) -> &mut Self

Overrides the dwDesiredAccess argument to the call to [CreateFile] with the specified value.

Source

fn share_mode(&mut self, val: u32) -> &mut Self

Overrides the dwShareMode argument to the call to [CreateFile] with the specified value.

Source

fn custom_flags(&mut self, flags: u32) -> &mut Self

Sets extra flags for the dwFileFlags argument to the call to CreateFile2 to the specified value (or combines it with attributes and security_qos_flags to set the dwFlagsAndAttributes for CreateFile).

Source

fn attributes(&mut self, val: u32) -> &mut Self

Sets the dwFileAttributes argument to the call to CreateFile2 to the specified value (or combines it with custom_flags and security_qos_flags to set the dwFlagsAndAttributes for CreateFile).

Source

fn security_qos_flags(&mut self, flags: u32) -> &mut Self

Sets the dwSecurityQosFlags argument to the call to CreateFile2 to the specified value (or combines it with custom_flags and attributes to set the dwFlagsAndAttributes for CreateFile).

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
