Struct OpenFlags 

pub struct OpenFlags {
    pub read: bool,
    pub write: bool,
    pub create: bool,
    pub truncate: bool,
    pub append: bool,
}

Flags for opening a file.

Controls how a file is opened: read/write mode, creation behavior, and truncation. Used with FsHandles::open.

Predefined Constants

Constant	Behavior
OpenFlags::READ	Read-only access
OpenFlags::WRITE	Write with create and truncate
OpenFlags::READ_WRITE	Read and write, file must exist
OpenFlags::APPEND	Append mode (writes go to end)

Fields

Field	Effect
read	Enable reading from file
write	Enable writing to file
create	Create file if it doesn’t exist
truncate	Truncate file to zero length on open
append	Writes always go to end of file

Example

use anyfs_backend::OpenFlags;

// Use predefined constants
let read_only = OpenFlags::READ;
assert!(read_only.read);
assert!(!read_only.write);

// Custom flags
let custom = OpenFlags {
    read: true,
    write: true,
    create: true,
    truncate: false,
    append: false,
};

Fields

read: bool

Open for reading.

write: bool

Open for writing.

create: bool

Create file if it doesn’t exist.

truncate: bool

Truncate file to zero length.

append: bool

Append to end of file.

Implementations

impl OpenFlags

pub const READ: Self

Read-only access.

pub const WRITE: Self

Write access with create and truncate.

pub const READ_WRITE: Self

Read and write access.

pub const APPEND: Self

Append mode - writes go to end of file.

Performs copy-assignment from source.

impl Debug for OpenFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OpenFlags

fn default() -> OpenFlags

Returns the “default value” for a type.
