Struct Clustering 

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

Configures table clustering.

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.

fields: Vec<String>

One or more fields on which data should be clustered. Only top-level, non-repeated, simple-type fields are supported. The ordering of the clustering fields should be prioritized from most to least important for filtering purposes.

For additional information, see Introduction to clustered tables.

Implementations

impl Clustering

pub fn new() -> Self

Creates a new default instance.

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

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

Sets the value of fields.

Example

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