Enum ConfigTier 

pub enum ConfigTier {
    System = 1,
    Local = 2,
    User = 3,
}

Configuration tier represents the priority level of a configuration source.

Tiers are ordered by priority: User > Local > System. When merging configurations, User tier overrides Local, and Local overrides System.

The enum’s discriminant values directly represent priority levels, allowing use via u8::from(tier) or tier as u8.

Variants

System = 1

System-wide configuration. Lowest priority, typically in /etc/. Examples: /etc/app/, /etc/xdg/app/

Local = 2

Local/machine-specific configuration. Medium priority, typically in /usr/local/etc or similar. Examples: /usr/local/etc/app/, /opt/app/etc/

User = 3

User-specific configuration. Highest priority, typically in user’s home directory. Examples: ~/.config/app/, ~/.apprc

Implementations

impl ConfigTier

pub const fn is_user(self) -> bool

Returns true if this tier is user-level.

pub const fn is_local(self) -> bool

Returns true if this tier is local-level.

pub const fn is_system(self) -> bool

Returns true if this tier is system-level.

Trait Implementations

impl Clone for ConfigTier

fn clone(&self) -> ConfigTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigTier

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

Formats the value using the given formatter.

impl Default for ConfigTier

fn default() -> ConfigTier

Returns the “default value” for a type.

impl From<ConfigTier> for u8

fn from(tier: ConfigTier) -> Self

Converts to this type from the input type.

impl Hash for ConfigTier

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ConfigTier

fn cmp(&self, other: &ConfigTier) -> 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,

Restrict a value to a certain interval.

impl PartialEq for ConfigTier

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

impl PartialOrd for ConfigTier

fn partial_cmp(&self, other: &ConfigTier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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.
