Struct Binding 

pub struct Binding { /* private fields */ }

Implementations

impl Binding

pub fn new( query: &str, parameters: &BTreeMap<String, Box<RawValue>>, engine: &Engine, caller: &Caller, allowance: &Allowance, form: Rows, ) -> Result<Self, Failure>

Bind the caller’s parameters; the fixed clock value travels in the token.

Errors

Refuses parameters that cannot be canonicalized or components that cannot be serialized for their digests.

pub fn validate(&self) -> Result<(), Failure>

Validate all component digests and their aggregate.

Errors

Returns query_continuation_invalid for a non-canonical digest or an inconsistent aggregate.

pub fn check(&self, expected: &Self) -> Result<(), Failure>

Check that this binding belongs to the expected request context.

Errors

Refuses invalid bindings or names the query, parameters, engine, caller or allowances that changed.
