Enum PermissionLevel 

#[repr(u8)]
pub enum PermissionLevel {
    None = 0,
    Read = 1,
    Write = 2,
    Execute = 3,
    Admin = 4,
}

Permission level that determines what operations are allowed.

Levels are hierarchical: a higher level automatically grants all lower levels. For example, Write permission implies Read permission.

Variants

None = 0

No permission granted

Read = 1

Read-only access: view contents, list directories, search

Write = 2

Read + create/modify: includes all Read operations plus file creation and modification

Execute = 3

Read + Write + execute: includes running commands and scripts

Admin = 4

Full access: includes all operations plus dangerous ones (delete, system commands)

Implementations

impl PermissionLevel

pub fn as_u8(self) -> u8

Returns the numeric value of this permission level.

pub fn from_u8(value: u8) -> Option<PermissionLevel>

Creates a permission level from a numeric value.

Returns None if the value is out of range (> 4).

pub fn satisfies(self, required: PermissionLevel) -> bool

Checks if this permission level satisfies a required level.

A level satisfies another if it is greater than or equal to the required level. This implements the permission hierarchy where higher levels imply lower levels.

Examples

use agent_core_runtime::permissions::PermissionLevel;

assert!(PermissionLevel::Write.satisfies(PermissionLevel::Read));
assert!(PermissionLevel::Admin.satisfies(PermissionLevel::Execute));
assert!(!PermissionLevel::Read.satisfies(PermissionLevel::Write));

pub fn implied_levels(self) -> Vec<PermissionLevel>

Returns all permission levels that this level implies.

For example, Write implies both Write and Read.

pub fn all() -> &'static [PermissionLevel]

Returns all permission levels as a slice.

Trait Implementations

Performs copy-assignment from source.

impl Copy for PermissionLevel

impl Debug for PermissionLevel

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

Formats the value using the given formatter.

impl Default for PermissionLevel

fn default() -> PermissionLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PermissionLevel

fn deserialize<__D>( __deserializer: __D, ) -> Result<PermissionLevel, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PermissionLevel

impl Hash for PermissionLevel

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for PermissionLevel

fn cmp(&self, other: &PermissionLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for PermissionLevel

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PermissionLevel

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
