§Note: This crate is renamed to `varing`.

const-varint

Protobuf’s varint encoding/decoding with full const context operations supports. (This project is renamed to varing)

LoC

§Installation

[dependencies]
const-varint = "0.4"

For u1, u2, u3, .., u127

const-varint = { version = "0.4", features = "arbitrary-int" }

For ruint::Uint<BITS, LBITS> support (not compatible in const context)
```
const-varint = { version = "0.4", features = ["ruint"] }
```

For primitive-types support (not compatible in const context)

const-varint = { version = "0.4", features = ["primitive-types"] }

For ethereum-types support (not compatible in const context)

const-varint = { version = "0.4", features = ["ethereum-types"] }
