Struct ReadRequest 

#[non_exhaustive]
pub struct ReadRequest {
    pub after: Option<Cursor>,
    pub limit: Option<u32>,
}

Request of usage.steps.read. Both members are optional and also accept null; any other member is refused malformed, and so does this type.

Without after, the read starts at the oldest row the feed still holds (the rows committed in the last 24 hours). limit defaults to 200; 0 is refused invalid_request and above 1,000 range_too_large. This type does not check limit: the provider does.

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.

after: Option<Cursor>

limit: Option<u32>

Implementations

impl ReadRequest

pub fn new() -> Self

A read from the oldest row the feed holds, with the default limit.

pub fn after(self, cursor: impl Into<Cursor>) -> Self

Reads the rows after cursor.

pub fn with_limit(self, limit: u32) -> Self

Asks for at most limit rows.
