Class `std.csv.CSVException`

Exception containing the row and column for when an exception was thrown.


						
				class CSVException
				
  : Exception
				;

Numbering of both row and col start at one and corresponds to the location in the file rather than any specified header. Special consideration should be made when there is failure to match the header see HeaderMismatchException for details.

When performing type conversions, ConvException is stored in the next field.

Fields

Name	Type	Description
`col`	`ulong`
`row`	`ulong`
`file`	`string`	The file name of the D source code corresponding with where the error was thrown from.
`info`	`object.Throwable.TraceInfo`	The stack trace of where the error happened. This is an opaque object that can either be converted to `string`, or iterated over with `foreach` to extract the items in the stack trace (as strings).
`line`	`ulong`	The line number of the D source code corresponding with where the error was thrown from.
`msg`	`string`	A message describing the error.

Properties

Name	Type	Description
`next`[get]	`inout(Throwable)`
`next`[set]	`Throwable`	Replace next in chain with `tail`. Use `chainTogether` instead if at all possible.

Methods

Name	Description
`chainTogether` ()	Append `e2` to chain of exceptions that starts with `e1`.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`message` ()	Get the message describing the error.
`opApply` (dg)	Loop over the chain of Throwables.
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides and overloads for `opEquals` should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for `null` on the typed overload.
`refcount` ()
`toHash` ()	Compute hash function for Object.
`toString` ()	Overrides `Object.toString` and returns the error message. Internally this forwards to the `toString` overload that takes a sink delegate.
`toString` ()	The Throwable hierarchy uses a toString overload that takes a sink delegate to avoid GC allocations, which cannot be performed in certain error situations. Override this `toString` method to customize the error message.

Example

import std.exception : collectException;
import std.algorithm.searching : count;
string text = "a,b,c\nHello,65";
auto ex = collectException!CSVException(csvReader(text).count);
// "(Row: 0, Col: 0) Row 2's length 2 does not match previous length of 3."
writeln(ex.toString);

Example

import std.exception : collectException;
import std.algorithm.searching : count;
import std.typecons : Tuple;
string text = "a,b\nHello,65";
auto ex = collectException!CSVException(csvReader!(Tuple!(string,int))(text).count);
// "(Row: 1, Col: 2) Unexpected 'b' when converting from type string to type int"
writeln(ex.toString);
