[−] Expand description

A GQL query.

Fields

query_string: String

[−] Expand description

A string of the format described here.

allow_literals: bool

[−] Expand description

When false, the query string must not contain any literals and instead must bind all values. For example, SELECT * FROM Kind WHERE a = 'string literal' is not allowed, while SELECT * FROM Kind WHERE a = @value is.

named_bindings: HashMap<String, GqlQueryParameter>

[−] Expand description

For each non-reserved named binding site in the query string, there must be a named parameter with that name, but not necessarily the inverse.

Key must match regex [A-Za-z_$][A-Za-z_$0-9]*, must not match regex __.*__, and must not be "".

positional_bindings: Vec<GqlQueryParameter>

[−] Expand description

Numbered binding site @1 references the first numbered parameter, effectively using 1-based indexing, rather than the usual 0.

For each binding site numbered i in query_string, there must be an i-th numbered parameter. The inverse must also be true.
