Cargo Features

[dependencies]
spanner-rs = { version = "0.3.0", default-features = false, features = ["json", "numeric", "temporal"] }
default = json, numeric, temporal

These default features are set whenever spanner-rs is added without default-features = false somewhere in the dependency tree.

json default = serde_json
numeric default = bigdecimal
temporal default = chrono

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

bigdecimal numeric

Enables bigdecimal ^0.3

chrono temporal
