Struct cap_fs_ext::OpenOptions

pub struct OpenOptions { /* fields omitted */ }

Re-export these to allow them to be used with Reuse. Options and flags which can be used to configure how a file is opened.

This corresponds to std::fs::OpenOptions.

Note that this OpenOptions has no open method. To open a file with an OptionOptions, you must first obtain a Dir containing the path, and then call Dir::open_with.

We need to define our own version because the libstd `OpenOptions` doesn't have public accessors that we can use.

Implementations

impl OpenOptions

Re-export these to allow them to be used with Reuse.

pub const fn new() -> OpenOptions

Creates a blank new set of options ready for configuration.

This corresponds to std::fs::OpenOptions::new.

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

Sets the option for read access.

This corresponds to std::fs::OpenOptions::read.

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

Sets the option for write access.

This corresponds to std::fs::OpenOptions::write.

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

Sets the option for the append mode.

This corresponds to std::fs::OpenOptions::append.

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

Sets the option for truncating a previous file.

This corresponds to std::fs::OpenOptions::truncate.
