Struct ListStreamsInput 

#[non_exhaustive]
pub struct ListStreamsInput {
    pub prefix: StreamNamePrefix,
    pub start_after: StreamNameStartAfter,
    pub limit: Option<usize>,
}

Input for list_streams operation.

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.

prefix: StreamNamePrefix

Filter streams whose names begin with this value.

Defaults to "".

start_after: StreamNameStartAfter

Filter streams whose names are lexicographically greater than this value.

Note: It must be greater than or equal to prefix.

Defaults to "".

limit: Option<usize>

Number of streams to return in a page. Will be clamped to a maximum of 1000.

Defaults to 1000.

Implementations

impl ListStreamsInput

pub fn new() -> Self
