Struct Protection

pub struct Protection(/* private fields */);

Represents memory protection flags.

This structure encapsulates read, write, and execute permissions for memory regions in a compact bit representation.

Implementations

impl Protection

pub const READ_BIT: u8 = 1u8

Bit flag representing read permission.

pub const WRITE_BIT: u8 = 2u8

Bit flag representing write permission.

pub const EXECUTE_BIT: u8 = 4u8

Bit flag representing execute permission.

pub const NONE: Self

No memory access permissions.

pub const READ: Self

Read-only memory access.

pub const WRITE: Self

Write-only memory access.

pub const EXECUTE: Self

Execute-only memory access.

pub const READ_WRITE: Self

Read and write memory access.

pub const READ_EXECUTE: Self

Read and execute memory access.

pub const WRITE_EXECUTE: Self

Write and execute memory access.

pub const READ_WRITE_EXECUTE: Self

Full memory access (read, write, and execute).

pub const fn new(read: bool, write: bool, execute: bool) -> Self

Creates a new protection type with specified permissions.

Parameters

• Read: Whether read permission is granted
• Write: Whether write permission is granted
• Execute: Whether execute permission is granted

Returns

A new protection type with the specified permissions.

pub const fn set_read(self, value: bool) -> Self

Sets or clears the read permission.

Parameters

• Value: Whether to grant or revoke read permission

Returns

A new protection type with the modified read permission.

pub const fn set_write(self, value: bool) -> Self

Sets or clears the write permission.

Parameters

• Value: Whether to grant or revoke write permission

Returns

A new protection type with the modified write permission.

pub const fn set_execute(self, value: bool) -> Self

Sets or clears the execute permission.

Parameters

• Value: Whether to grant or revoke execute permission

Returns

A new protection type with the modified execute permission.

pub const fn get_read(&self) -> bool

Checks if read permission is granted.

Returns

true if read permission is granted, false otherwise.

pub const fn get_write(&self) -> bool

Checks if write permission is granted.

Returns

true if write permission is granted, false otherwise.

pub const fn get_execute(&self) -> bool

Checks if execute permission is granted.

Returns

true if execute permission is granted, false otherwise.

pub const fn as_u8(&self) -> u8

Converts the protection type to its raw u8 representation.

Returns

The raw byte value representing the protection flags.

pub const fn from_u8(value: u8) -> Self

Creates a new protection type from a raw u8 value.

Parameters

• Value: The raw protection flags

Returns

A new protection type with the specified flags.

Trait Implementations

impl Clone for Protection

fn clone(&self) -> Protection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Protection

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

Formats the value using the given formatter.

impl From<Protection> for u8

fn from(protection: Protection) -> Self

Converts to this type from the input type.

impl From<u8> for Protection

fn from(protection: u8) -> Self

Converts to this type from the input type.

impl PartialEq for Protection

fn eq(&self, other: &Protection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
