Struct Param 

#[non_exhaustive]
pub struct Param {
    pub name: String,
    pub cql_type: CqlType,
    pub nullable: bool,
    pub source: ParamSource,
    pub span: Span,
}

One bind parameter of a query.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Unique within the query; derived from the column (or limit, ttl, timestamp, …).

cql_type: CqlType

The type the driver must bind.

nullable: bool

Whether the caller may pass NULL for this value. This concerns bind values only and is independent of result nullability.

source: ParamSource

What the marker stands for.

span: Span

Position of the ? in the source.
