Variants

OTHER

Unspecified, application-specific metadata. Maps to an unspecified {@link Object}.

ORIENTATION

Denotes the likely approximate orientation of the barcode in the image. This value is given as degrees rotated clockwise from the normal, upright orientation. For example a 1D barcode which was found by reading top-to-bottom would be said to have orientation “90”. This key maps to an {@link Integer} whose value is in the range [0,360).

BYTE_SEGMENTS

2D barcode formats typically encode text, but allow for a sort of 'byte mode' which is sometimes used to encode binary data. While {@link RXingResult} makes available the complete raw bytes in the barcode for these formats, it does not offer the bytes from the byte segments alone.

This maps to a {@link java.util.List} of byte arrays corresponding to the raw bytes in the byte segments in the barcode, in order.

ERROR_CORRECTION_LEVEL

Error correction level used, if applicable. The value type depends on the format, but is typically a String.

ISSUE_NUMBER

For some periodicals, indicates the issue number as an {@link Integer}.

SUGGESTED_PRICE

For some products, indicates the suggested retail price in the barcode as a formatted {@link String}.

POSSIBLE_COUNTRY

For some products, the possible country of manufacture as a {@link String} denoting the ISO country code. Some map to multiple possible countries, like “US/CA”.

UPC_EAN_EXTENSION

For some products, the extension text

PDF417_EXTRA_METADATA

PDF417-specific metadata

STRUCTURED_APPEND_SEQUENCE

If the code format supports structured append and the current scanned code is part of one then the sequence number is given with it.

STRUCTURED_APPEND_PARITY

If the code format supports structured append and the current scanned code is part of one then the parity is given with it.

SYMBOLOGY_IDENTIFIER

Barcode Symbology Identifier. Note: According to the GS1 specification the identifier may have to replace a leading FNC1/GS character when prepending to the barcode content.

Trait Implementations

impl Clone for RXingResultMetadataType

fn clone(&self) -> RXingResultMetadataType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RXingResultMetadataType

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

Formats the value using the given formatter.

impl From<String> for RXingResultMetadataType

fn from(in_str: String) -> Self

Converts to this type from the input type.

impl Hash for RXingResultMetadataType

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

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 PartialEq<RXingResultMetadataType> for RXingResultMetadataType

fn eq(&self, other: &RXingResultMetadataType) -> 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.
