Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_data_length: usize,
    pub max_version: Version,
    pub max_render_size: (u32, u32),
    pub encoding_timeout: Option<u64>,
}

Explicit resource budgets for bounded QR-code construction.

QrCode::with_limits applies these limits before allocating encoder state and after selecting the resulting symbol dimensions. With the facade crate’s std feature, encoding_timeout is checked at synchronous construction boundaries. It is not a preemptive interrupt for an in-flight CPU step. The dimensions are the maximum width and height of the symbol passed to a renderer; a renderer may impose a stricter pixel budget of its own.

Fields

max_data_length: usize

Maximum number of input bytes accepted before parsing or allocation.

max_version: Version

Maximum normal QR version considered by automatic version selection.

max_render_size: (u32, u32)

Maximum (width, height) accepted for the generated module symbol.

encoding_timeout: Option<u64>

Optional synchronous encoding timeout budget in milliseconds.

None disables timeout checks. Some(0) is rejected as a malformed budget because it cannot describe useful work.

Implementations

impl ResourceLimits

pub const fn new( max_data_length: usize, max_version: Version, max_render_size: (u32, u32), ) -> ResourceLimits

Creates an explicit resource budget.

pub const fn with_encoding_timeout_millis( self, timeout_ms: u64, ) -> ResourceLimits

Returns this budget with an encoding timeout in milliseconds.

The facade crate enforces this budget at synchronous construction boundaries when std is enabled.

pub fn validate(self) -> Result<(), QrError>

Validates the shape of this budget without inspecting input data.

Automatic construction currently targets normal QR versions, so Micro versions are rejected here rather than being silently interpreted as a normal-version cap. Zero render dimensions cannot describe a symbol.
