bigint
bigint is a wrapper around math/big package to let us use big.int type in postgresql.
This project is forked from https://github.com/d-fal/bigint.
Example use with go-pg
go-pg is an amazing orm for gophers to utilize postgres. This package is used to help go-pg users implement math/big functionalities.
package main
import (
"github.com/iam047801/bigint"
"github.com/go-pg/pg/v10"
"github.com/go-pg/pg/v10/orm"
)
func main() {
type UserBalance struct {
tableName struct{} `pg:"balances"`
UserID uint64 `pg:",pk"`
Value *bigint.BigInt `pg:"type:numeric"`
}
db := pg.Connect(&pg.Options{
Addr: "127.0.0.1:5432",
User: "postgres",
Password: "postgres",
Database: "postgres",
})
err := db.Model((*UserBalance)(nil)).CreateTable(&orm.CreateTableOptions{
Temp: true,
FKConstraints: true,
IfNotExists: true,
})
if err != nil {
panic(err)
}
}

Types ¶
type BigInt ¶
func FromString ¶
FromString allocates and returns a new BigInt set to x, interpreted in the base 10.
func (*BigInt) Bytes ¶
Bytes returns the absolute value of x as a big-endian byte slice.
To use a fixed length slice, or a preallocated one, use FillBytes.
func (*BigInt) Div ¶
Div sets new BigInt to the quotient x/y for y != 0 and returns it. If y == 0, a division-by-zero run-time panic occurs.
func (*BigInt) MarshalJSON ¶
func (*BigInt) String ¶
String returns the decimal representation of x as generated by x.ToBigInt().Text(10).
func (*BigInt) ToInt64 ¶
ToInt64 returns the int64 representation of x. If x cannot be represented in an int64, the result is undefined.
func (*BigInt) ToUInt64 ¶
ToUInt64 returns the uint64 representation of x. If x cannot be represented in a uint64, the result is undefined.
