All errors that can occur when attempting to parse a PNM
Variants§
PnmMagicInvalid([u8; 2])
PNM’s “P[123456]” signature wrong or missing
UnparsableValue(ErrorDataSource, String, ParseIntError)
Couldn’t parse the specified string as an integer from the specified source
NonAsciiByteInHeader(u8)
More than the exactly one allowed plane specified by the format
NonAsciiLineInPamHeader
The PAM header contained a non-ASCII byte
NonAsciiSample
A sample string contained a non-ASCII byte
NotNewlineAfterP7Magic(u8)
The byte after the P7 magic was not 0x0A NEWLINE
UnexpectedPnmHeaderEnd
The PNM header had too few lines
HeaderLineDuplicated(PnmHeaderLine)
The specified line was specified twice
HeaderLineUnknown(String)
The line with the specified ID was not understood
HeaderLineMissing
At least one of the required lines were missing from the header (are None
here)
Same names as PnmHeaderLine
InputTooShort
Not enough data was provided to the Decoder to decode the image
UnexpectedByteInRaster(u8)
Sample raster contained unexpected byte
SampleOutOfBounds(u8)
Specified sample was out of bounds (e.g. >1 in B&W)
MaxvalZero
The image’s maxval is zero
MaxvalTooBig(u32)
The image’s maxval exceeds 0xFFFF
InvalidDepthOrMaxval
The specified tuple type supports restricted depths and maxvals, those restrictions were not met
InvalidDepth
The specified tuple type supports restricted depths, those restrictions were not met
TupleTypeUnrecognised
The tuple type was not recognised by the parser
Overflow
Overflowed the specified value when parsing
