Struct FileOpenOptions 

pub struct FileOpenOptions {
    pub read: bool,
    pub write: bool,
    pub create: bool,
    pub append: bool,
    pub truncate: bool,

Open for reading.

write: bool

Open for writing.

create: bool

Create the file if it does not exist.

append: bool

Append instead of overwriting.

truncate: bool

Truncate existing content.

Read-write access (creates if absent, preserves existing content).

pub const fn read_write_truncate() -> FileOpenOptions

Read-write access that truncates existing content (creates if absent).
