Struct BranchPath 

pub struct BranchPath {
    pub dewey: AverStr,
}

BranchPath — opaque dewey-decimal identifier for a branch in the structural tree of !/?! groups. In the VM/interpreter it is a built-in record { dewey: String }; it surfaces in source only as the first parameter of Oracle-proof stub functions (oracle : (BranchPath, Int, args...) -> T). Those stub fns are emitted by the Rust backend as ordinary (dead-at-runtime) functions because module-level fns are emitted regardless of reachability, so the type must be in scope for them to compile. It is never produced or consumed by runtime code — only aver verify exercises the Oracle laws — so the constructors here only need to compile.

Fields

dewey: AverStr

Implementations

impl BranchPath

pub fn root() -> Self

Canonical root path (empty dewey). Mirrors BranchPath.Root in src/types/branch_path.rs.

pub fn child(path: &BranchPath, idx: i64) -> Self

Extend a path by entering branch idx of a group. Mirrors BranchPath.child (dewey segments joined with .).

pub fn parse(raw: &str) -> Self

Parse a dewey-decimal path string. Mirrors BranchPath.parse.

Trait Implementations

impl AverDisplay for BranchPath

fn aver_display(&self) -> String

fn aver_display_inner(&self) -> String

impl Clone for BranchPath

fn clone(&self) -> BranchPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BranchPath

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

Formats the value using the given formatter.

impl Eq for BranchPath

impl Hash for BranchPath

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 BranchPath

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

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

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