Package-Level Type Names (only one)


	/* sort by:  |  */
	
		A ValueParser enables parsing a single string into a variety of data types
		in a concise and safe way. The Err method must be invoked after invoking
		any other methods to ensure a value was successfully parsed.

		
			
				Err returns the last error, if any, encountered by the ValueParser.

			
				Int interprets the underlying value as an int and returns that value.

			
				PInt64 interprets the underlying value as an int64 and returns a pointer to
				that value.

			
				PUInt64 interprets the underlying value as an uint64 and returns a pointer to
				that value.

		
			func NewValueParser(v string) *ValueParser




Package-Level Functions (total 13)


	
		NewValueParser creates a ValueParser using the input string.


	
		ParseBool parses a string into a boolean pointer.


	
		Parses a uint64 from given hex in string.


	
		ParsePInt64s parses a slice of strings into a slice of int64 pointers.


	
		ParseUint32s parses a slice of strings into a slice of uint32s.


	
		ParseUint64s parses a slice of strings into a slice of uint64s.


	
		ReadFileNoStat uses io.ReadAll to read contents of entire file.
		This is similar to os.ReadFile but without the call to os.Stat, because
		many files in /proc and /sys report incorrect file sizes (either 0 or 4096).
		Reads a max file size of 1024kB.  For files larger than this, a scanner
		should be used.


	
		ReadHexFromFile reads a file and attempts to parse a uint64 from a hexadecimal format 0xXX.


	
		ReadIntFromFile reads a file and attempts to parse a int64 from it.


	
		ReadUintFromFile reads a file and attempts to parse a uint64 from it.


	
		SysReadFile is a simplified os.ReadFile that invokes syscall.Read directly.
		https://github.com/prometheus/node_exporter/pull/728/files
		
		Note that this function will not read files larger than 128 bytes.


	
		SysReadIntFromFile reads a file using SysReadFile and attempts to parse a int64 from it.


	
		SysReadUintFromFile reads a file using SysReadFile and attempts to parse a uint64 from it.
