Struct OpenOptions 

pub struct OpenOptions { /* private fields */ }

Options and flags which can be used to configure how a file is opened.

Mirrors std::fs::OpenOptions without leaking the standard library type into the abstraction.

Implementations

impl OpenOptions

pub fn new() -> Self

Creates a blank new set of options.

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

Sets the option for read access.

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

Sets the option for write access.

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

Sets the option for append mode.

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

Sets the option to truncate the file.

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

Sets the option to create the file if it does not exist.

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

Sets the option to create a new file, failing if it already exists.

pub fn get_read(&self) -> bool

Returns whether read access is enabled.

pub fn get_write(&self) -> bool

Returns whether write access is enabled.

pub fn get_append(&self) -> bool

Returns whether append mode is enabled.

Returns whether truncation is enabled.

pub fn get_create(&self) -> bool

Returns whether creating the file is enabled.

pub fn get_create_new(&self) -> bool
