stringutils
Some string utils
UnsafeString([]byte) string return unsafe string from bytes slice indirectly (without allocation)
UnsafeStringFromPtr(*byte, length) string return unsafe string from bytes slice pointer indirectly (without allocation)
UnsafeStringBytes(*string) []bytes return unsafe string bytes indirectly (without allocation)
Split2(s string, sep string) (string, string, int) Split2 return the split string results (without memory allocations). Use Index for find separator.
SplitN(s string, sep string, buf []string) ([]string, int) // SplitN return splitted slice (use pre-allocated buffer) and end position (for detect if string contains more fields for split). Use Index for find separator.
Builder very simular to strings.Builder, but has better perfomance (at golang 1.14).
Template is a simple templating system

Functions ¶
func Split2 ¶
Split2 return the split string results (without memory allocations)
If sep string not found: 's' '' 1 If s or sep string is empthy: 's' '' 1 In other cases: 's0' 's2' 2
func SplitN ¶
SplitN return splitted slice (use pre-allocated buffer) and end position (for detect if string contains more fields for split)
func UnsafeString ¶
UnsafeString returns the string under byte buffer
func UnsafeStringBytes ¶
UnsafeStringBytes returns the string bytes
func UnsafeStringFromPtr ¶
UnsafeStringFromPtr returns the string with specific length under byte buffer
Types ¶
type Builder ¶
type Builder struct {
// contains filtered or unexported fields
}
A Builder is used to efficiently build a string using Write methods (with better perfomance than strings.Builder). It minimizes memory copying. The zero value is ready to use. Do not copy a non-zero Builder.
func (*Builder) Cap ¶
Cap returns the capacity of the builder's underlying byte slice. It is the total space allocated for the string being built and includes any bytes already written.
func (*Builder) Grow ¶
Grow grows b's capacity, if necessary, to guarantee space for another n bytes. After Grow(n), at least n bytes can be written to b without another allocation.
func (*Builder) Map ¶
based on strings.Map Map returns a copy of the string s with all its characters modified according to the mapping function. If mapping returns a negative value, the character is dropped from the string with no replacement.
func (*Builder) Release ¶
func (sb *Builder) Release()
Release resets the Builder to be empty and free buffer
func (*Builder) WriteBytes ¶
WriteBytes appends the contents of p to b's buffer.
func (*Builder) WriteFloat ¶
WriteFloat appends the string form of the floating-point number f, as generated by FormatFloat, to dst and returns the extended buffer.
func (*Builder) WriteInt ¶
WriteInt appends the string form of the integer i, as generated by FormatInt, to dst and returns the extended buffer.
func (*Builder) WriteRune ¶
WriteRune appends the UTF-8 encoding of Unicode code point r to b's buffer.
func (*Builder) WriteString ¶
WriteString appends the contents of s to b's buffer.
func (*Builder) WriteStringLower ¶
based on strings.ToLower ToLower returns s with all Unicode letters mapped to their lower case.
func (*Builder) WriteStringUpper ¶
based on strings.ToUpper ToUpper returns s with all Unicode letters mapped to their upper case.
type Template ¶
type Template []interface{}
Template parsed and splited format string (stored in first field)
func InitTemplate ¶
InitTemplate parse and split format string (format string stored in first field)
@format Format string like 'string %{param} %{param1.param2}'
