Struct mini_functions::qr::QRCode

#[non_exhaustive]
pub struct QRCode {
    pub data: Vec<u8>,
}

Re-exported main qrc module from qrc for QR code generation. QRCode is a structure that contains data in the form of a vector of bytes.

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.

data: Vec<u8>

The data field holds the data to be encoded in the QR code.

Implementations

impl QRCode

Implementation of QRCode structure.

pub fn new(data: Vec<u8>) -> QRCode

Creates a new QRCode structure with the given data.

pub fn from_string(data: String) -> QRCode

The from_string method creates a new instance of the QRCode struct by converting the given string data into a vector of bytes

pub fn from_bytes(data: Vec<u8>) -> QRCode

Creates a new QRCode structure from a vector of bytes.

pub fn to_qrcode(&self) -> QrCode

Converts the QRCode structure to a QrCode structure.

pub fn to_png(&self, width: u32) -> ImageBuffer<Rgba<u8>, Vec<u8>>

Converts the QRCode structure to a PNG image.

pub fn to_jpg(&self, width: u32) -> ImageBuffer<Rgba<u8>, Vec<u8>>

Converts the QRCode structure to a JPG image.

pub fn to_gif(&self, width: u32) -> ImageBuffer<Rgba<u8>, Vec<u8>>

Converts the QRCode structure to a GIF image.

pub fn to_svg(&self, width: u32) -> String

Converts the QRCode structure to an SVG image.

pub fn colorize(&self, color: Rgba<u8>) -> ImageBuffer<Rgba<u8>, Vec<u8>>

The colorize method creates a new PNG image of the QR code using the data stored in the QRCode and the given color value to colorize the QR code.

pub fn resize(&self, width: u32, height: u32) -> ImageBuffer<Rgba<u8>, Vec<u8>>

The resize method creates a new PNG image of the QR code using the data stored in the QRCode and the given width and height values to resize the QR code.

pub fn add_image_watermark( img: &mut ImageBuffer<Rgba<u8>, Vec<u8>>, watermark: &ImageBuffer<Rgba<u8>, Vec<u8>> )

The add_image_watermark method adds a watermark to the given image.

Trait Implementations

impl Clone for QRCode

fn clone(&self) -> QRCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QRCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for QRCode

fn default() -> QRCode

Returns the “default value” for a type.

impl Hash for QRCode

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for QRCode

fn cmp(&self, other: &QRCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for QRCode

fn eq(&self, other: &QRCode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for QRCode

fn partial_cmp(&self, other: &QRCode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
