Struct StoreSlice 

pub struct StoreSlice {
    pub name: String,
    pub source_root: String,
    pub name_pattern: String,
    pub max_entries: usize,
    pub max_size_bytes: u64,
}

Typed declaration of “a subset of /nix/store” for operations. Lisp surface: (defstore-slice …).

Fields

name: String

Stable name (used in reports + tests).

source_root: String

Source store root (typically /nix/store).

name_pattern: String

Selection predicate — a regex over the basename. Matches every path whose name (e.g. 0mrdxm84...-source) matches.

max_entries: usize

Maximum entries to include from the source. Prevents disk-blowup when probing large stores.

max_size_bytes: u64

Skip entries larger than this size (bytes) — avoids rematerializing massive sources. 0 = unlimited.

Trait Implementations

impl Clone for StoreSlice

fn clone(&self) -> StoreSlice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreSlice

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StoreSlice

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl HasName for StoreSlice

fn name(&self) -> &str

impl Serialize for StoreSlice

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spec for StoreSlice

const CANONICAL_LISP: &'static str = crate::store_ops::CANONICAL_STORE_OPS_LISP

The embedded canonical Lisp source for this domain. Wrapped over include_str! in the domain’s own module.

fn load_canonical_all() -> Result<Vec<Self>, SpecError>

Compile the canonical source and return every authored instance. Default impl threads through crate::loader::load_all; domains generally don’t need to override.

fn load_named(name: &str) -> Result<Self, SpecError>

where Self: HasName,

Look up the canonical instance with the given name. Default impl scans load_canonical_all linearly; domains that store many instances may override with a hashmap.

impl TataraDomain for StoreSlice

const KEYWORD: &'static str = "defstore-slice"

The Lisp keyword (e.g., "defmonitor").

fn compile_from_args(args: &[Sexp]) -> Result<Self>

Parse the argument list (everything after the keyword) into Self.

fn compile_from_sexp(form: &Sexp) -> Result<Self, LispError>

Parse a complete form; validates the head symbol matches KEYWORD.
