Struct ProtectFlags 

#[non_exhaustive]
pub struct ProtectFlags {
    pub read: bool,
    pub write: bool,
    pub exec: bool,
}

Memory protection bits passed to OsBacked::protect.

#[non_exhaustive] so future hardware-protection primitives can add bits (PROT_MTE tag enable, MPK key index, PROT_GROWSDOWN) without breaking downstream callers. Construct via the provided NONE / RW / READ / RX constants — never with a struct literal.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

read: bool

Region is readable.

write: bool

Region is writable.

exec: bool

Region is executable.

Implementations

impl ProtectFlags

pub const NONE: ProtectFlags

No access. Reads and writes fault.

pub const RW: ProtectFlags

Read + write, no execute. The standard data-region setting.

pub const READ: ProtectFlags

Read only.

pub const RX: ProtectFlags

Read + execute, no write. The standard code-region setting.

Trait Implementations

impl Clone for ProtectFlags

fn clone(&self) -> ProtectFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtectFlags

impl Debug for ProtectFlags

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

Formats the value using the given formatter.

impl Eq for ProtectFlags

impl PartialEq for ProtectFlags

fn eq(&self, other: &ProtectFlags) -> 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.
