Struct PreferredCrates 

pub struct PreferredCrates {
    pub date_time: DateTimeCrate,
    pub numeric: NumericCrate,
}

Available on crate feature _unstable-docs only.

Fields

date_time: DateTimeCrate

Specify the crate to use for mapping date/time types to Rust.

The default behavior is to use whatever crate is enabled, chrono or time (the latter takes precedent).

Example: Always Use Chrono

Thanks to Cargo’s feature unification, a crate in the dependency graph may enable the time feature of SQLx which will force it on for all crates using SQLx, which will result in problems if your crate wants to use types from chrono.

You can use the type override syntax (see sqlx::query! for details), or you can force an override globally by setting this option.

sqlx.toml

[macros.preferred-crates]
date-time = "chrono"

numeric: NumericCrate

Specify the crate to use for mapping NUMERIC types to Rust.

The default behavior is to use whatever crate is enabled, bigdecimal or rust_decimal (the latter takes precedent).

Example: Always Use bigdecimal

Thanks to Cargo’s feature unification, a crate in the dependency graph may enable the rust_decimal feature of SQLx which will force it on for all crates using SQLx, which will result in problems if your crate wants to use types from bigdecimal.

You can use the type override syntax (see sqlx::query! for details), or you can force an override globally by setting this option.

sqlx.toml

[macros.preferred-crates]
numeric = "bigdecimal"
