Struct BatchRender 

pub struct BatchRender<'a> { /* private fields */ }

Builder for rendering a slice of QrCode values into stable, named in-memory outputs.

Implementations

impl<'a> BatchRender<'a>

pub fn new(codes: &'a [QrCode]) -> Self

Creates a batch-render builder for codes.

pub fn prefix(self, prefix: impl Into<String>) -> Self

Sets the output name prefix.

pub fn extension(self, extension: impl Into<String>) -> Self

Sets the output extension. A leading dot is accepted and stripped.

Pass an empty string to omit the extension.

pub const fn start_index(self, start_index: usize) -> Self

Sets the first numeric index used in generated names.

pub const fn index_width(self, index_width: usize) -> Self

Sets the minimum zero-padded index width.

pub const fn quiet_zone(self, quiet_zone: bool) -> Self

Sets whether rendered symbols include their quiet zone.

pub const fn module_dimensions(self, width: u32, height: u32) -> Self

Sets fixed module dimensions for every rendered output.

pub const fn default_module_dimensions(self) -> Self

Clears fixed module dimensions, returning to the renderer default.

pub fn build<P: Pixel>(&self) -> Vec<BatchRendered<P::Image>>

Render every code in order.

Trait Implementations

impl<'a> Clone for BatchRender<'a>

fn clone(&self) -> BatchRender<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
