Struct ResourceLimits 

pub struct ResourceLimits {
    pub max_data_length: usize,
    pub max_version: Version,
    pub max_render_size: (u32, u32),
}

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. 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.

Implementations

impl ResourceLimits

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

Creates an explicit resource budget.

pub fn validate(self) -> QrResult<()>

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.
