Struct ExplainQueryStep 

#[non_exhaustive]
pub struct ExplainQueryStep {
    pub kind: String,
    pub substeps: Vec<String>,
    /* private fields */
}

An operation within a stage.

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.

kind: String

Machine-readable operation type.

substeps: Vec<String>

Human-readable description of the step(s).

Implementations

impl ExplainQueryStep

pub fn new() -> Self

Creates a new default instance.

pub fn set_kind<T: Into<String>>(self, v: T) -> Self

Sets the value of kind.

Example

let x = ExplainQueryStep::new().set_kind("example");

pub fn set_substeps<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of substeps.

Example

let x = ExplainQueryStep::new().set_substeps(["a", "b", "c"]);
