Struct StringLimitsBuilder 

pub struct StringLimitsBuilder<R, Q = u64>
where
    Q: ResourceQuantity,
{ /* private fields */ }

Builder for StringLimits.

Type Parameters

• R - Caller-defined resource identity retained by limits and errors.
• Q - Exact unsigned quantity used for measurements and accounting.

Examples

use qubit_budget::ResourceLimit;
use qubit_budget::StringLimitsBuilder;

let limits = StringLimitsBuilder::new()
    .utf8_bytes_limit(ResourceLimit::new("string bytes", 4_u64))
    .build();
assert_eq!(limits.utf8_bytes_limit().unwrap().maximum(), 4);

Implementations

impl<R, Q> StringLimitsBuilder<R, Q>

where Q: ResourceQuantity,

pub const fn new() -> Self

Creates an empty string-limits builder.

Returns

Creates an empty string-limits builder.

pub fn utf8_bytes_limit(self, limit: ResourceLimit<R, Q>) -> Self

Sets the inclusive UTF-8 byte limit.

Parameters

• limit - Resource-bound UTF-8 byte limit to install.

Returns

The builder with the described setting applied.

pub fn build(self) -> StringLimits<R, Q>

Builds the configured string limits.

Returns

Builds the configured string limits.
