Struct OpenOptions

pub struct OpenOptions {

    pub create: bool,
    pub create_new: bool,

Transparent replica of OpenOptions

This is a replica of OpenOptions. Please see it’s documentation for what which option means and how they interact.

There are From implementations to cast between this type and fs::OpenOptions back and forth, but you shouldn’t rely on the cast from fs::OpenOptions to this type to be stable and always successful.

Fields

read: bool

write: bool

append: bool

truncate: bool

create: bool

create_new: bool

Implementations

impl OpenOptions

pub const fn new() -> Self

Creates a new OpenOptions

Creates a new all-false OpenOptions.

pub fn read(&mut self, flag: bool) -> Self

Sets the read flag

This function sets or resets the read flag and returns a copy of it to enable method-style function chains.

pub fn write(&mut self, flag: bool) -> Self

Sets the write flag

This function sets or resets the write flag and returns a copy of it to enable method-style function chains.

pub fn append(&mut self, flag: bool) -> Self

Sets the append flag

This function sets or resets the append flag and returns a copy of it to enable method-style function chains.

pub fn truncate(&mut self, flag: bool) -> Self

Sets the truncate flag

This function sets or resets the truncate flag and returns a copy of it to enable method-style function chains.

pub fn create(&mut self, flag: bool) -> Self

Sets the create flag

This function sets or resets the create flag and returns a copy of it to enable method-style function chains.

pub fn create_new(&mut self, flag: bool) -> Self

Sets the create_new flag

This function sets or resets the create_new flag and returns a copy of it to enable method-style function chains.
