Struct QueryPlan 

pub struct QueryPlan {
    pub sql: String,
    pub values: Vec<Value>,
    pub stream: String,
    pub sessions: Vec<String>,
    pub params: QueryParams,
    pub timeout: Duration,
    pub limit: usize,
}

A validated query, ready for a backend to prepare and bind.

The SQL here is the caller’s with every parameter rewritten to a bare ?, and QueryPlan::values is what those placeholders bind to, in order — the only difference between this text and what was passed in.

Fields

sql: String

The statement to prepare. Every parameter in it is a bare ?.

values: Vec<Value>

What the ? placeholders bind to, in the order they appear.

stream: String

What $stream resolved to: the session’s own stream.

sessions: Vec<String>

What $sessions expanded to, in order.

params: QueryParams

The caller’s own values, as they were given.

timeout: Duration

The deadline for the whole query.

limit: usize

The row cap.
