Enum CacheRootKind 

#[repr(i32)]
pub enum CacheRootKind {
    Unspecified = 0,
    CacheData = 1,
    CacheLogs = 2,
    CacheLocks = 3,
    CacheRuntime = 4,
    CacheTmp = 5,
    CacheConfig = 6,
    CacheIndex = 7,
    CacheJournal = 8,
    CacheSecrets = 9,
}

Logical role classification for cache roots. Wire values mirror v1’s broker_v1.CacheRootKind EXACTLY (see broker_v1_manifest.proto). Keeping the integer values aligned avoids subtle bugs when consumers mix the two generations (e.g. via as i32 casts in test fixtures or in code that bridges between v1 and v2). New kinds land in the reserved range; v1’s enum is FROZEN so anything past 9 is v2-only.

Variants

Unspecified = 0

Unknown / unset (proto3 zero value). Consumers MUST treat this as “ignore” rather than a real cache role.

CacheData = 1

Primary cache data (the largest root; sccache-style content store).

CacheLogs = 2

Log directory (daemon stderr / structured event log).

CacheLocks = 3

PID files, lock files, sockets, manifests, identity JSON.

CacheRuntime = 4

Copied daemon binaries (relocated install destination).

CacheTmp = 5

Temporary / ephemeral working tree (artifact build scratch, depfile staging, repeatedly emptied).

CacheConfig = 6

User config (do NOT prune).

CacheIndex = 7

Separately bounded index (redb, depgraph snapshot, compile journal).

CacheJournal = 8

WAL files needing separate fsync semantics.

CacheSecrets = 9

API keys / tokens. mode 0600. NEVER LOGGED.

Implementations

impl CacheRootKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of CacheRootKind.

pub fn from_i32(value: i32) -> Option<CacheRootKind>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a CacheRootKind, or None if value is not a valid variant.

impl CacheRootKind

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for CacheRootKind

fn clone(&self) -> CacheRootKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CacheRootKind

impl Debug for CacheRootKind

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

Formats the value using the given formatter.

impl Default for CacheRootKind

fn default() -> CacheRootKind

Returns the “default value” for a type.

impl Eq for CacheRootKind

impl From<CacheRootKind> for i32

fn from(value: CacheRootKind) -> i32

Converts to this type from the input type.

impl Hash for CacheRootKind

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 CacheRootKind

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

fn eq(&self, other: &CacheRootKind) -> 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 CacheRootKind

fn partial_cmp(&self, other: &CacheRootKind) -> 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.

impl StructuralPartialEq for CacheRootKind

impl TryFrom<i32> for CacheRootKind

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<CacheRootKind, UnknownEnumValue>

Performs the conversion.
