Struct Recording 

pub struct Recording<'a> { /* private fields */ }

A Resolver that forwards to another and records each call, in order.

Implementations

impl<'a> Recording<'a>

pub fn new(inner: &'a dyn Resolver) -> Recording<'a>

Records the calls made to inner.

pub fn calls(&self) -> Vec<Call>

The calls recorded so far.

pub fn take(&self) -> Vec<Call>

The calls recorded so far, clearing the record.

Trait Implementations

impl Debug for Recording<'_>

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

Formats the value using the given formatter.

impl Resolver for Recording<'_>

fn descriptor(&self, fn_hash: &str) -> Option<Cow<'_, [u8]>>

The descriptor JSON text offered for fn_hash, or None if unavailable (E_FN_UNAVAILABLE). Only None is unavailability: the text is parsed strictly (unparseable text reports its parse code), and any other JSON value, null included, is a descriptor offered that fails the hash check (E_FN_HASH_MISMATCH, SPEC 10.1 step 7.1).

fn receipt(&self, hash: &str) -> Option<Cow<'_, [u8]>>

The receipt JSON text offered for receipt hash hash, or None if unavailable (E_INPUT_UNAVAILABLE).

fn evaluate(&self, cell: &Cell, asof: &str) -> Option<Scalar>

The value of evaluating cell as of asof (for stored: the value looked up as of it, SPEC 10.1 step 7.6), or None if this resolver cannot evaluate it: no runtime for the language, a budget exceeded, inputs the evaluator cannot obtain (E_EVAL_UNAVAILABLE, see VerifyResult). asof is the receipt’s asof.

fn manifest(&self, entry: &str) -> Option<Cow<'_, [u8]>>

The manifest JSON text offered for slice entry entry (slice:<slice id>:<members hash>), or None if unavailable (E_INPUT_UNAVAILABLE). The text is parsed strictly and checked as a Manifest; one that does not hash to the entry is E_INPUT_UNAVAILABLE, as a receipt with another hash. Provided: None.

fn evaluation(&self, cell: &Cell, asof: &str) -> Option<Evaluation>

Evaluates cell as of asof, with the evaluation’s lineage when the resolver has it: the inputs entries the evaluation read (10.1 step 7.6). verify calls this once, in place of evaluate. When the value differs from the receipt’s, a lineage that replaces one of the receipt’s inputs by a later version of the same cell (whose receipt it offers through receipt), or one of its slice entries by an item beginning slice:<the same slice id>:, makes the result E_INPUT_SUPERSEDED instead of E_VALUE_MISMATCH. Provided: evaluate’s value, with no lineage.
