Struct WindowAllowlist 

pub struct WindowAllowlist { /* private fields */ }

Validated allowlist of identifiers permitted in window queries for a given type.

Built at request-planning time from the compiled schema’s FactTableMetadata. An empty allowlist means “no schema constraints are declared; character-level validation still applies”.

Implementations

impl WindowAllowlist

pub fn from_metadata(metadata: &FactTableMetadata) -> Self

Build an allowlist from compiled fact-table metadata.

pub fn is_empty(&self) -> bool

Returns true if no schema constraints are declared.

An empty allowlist does not block any identifier; character-level validation in the planner still applies.

pub fn validate(&self, identifier: &str, context: &str) -> Result<()>

Validate that identifier is in the allowlist.

When the allowlist is empty (no schema constraints), this is a no-op.

Errors

Returns FraiseQLError::Validation if the identifier is not in the allowlist and the allowlist is non-empty.
