Struct ResolveConfig 

pub struct ResolveConfig { /* private fields */ }

Available on crate feature migrate only.

Configuration for migration resolution using ResolveWith.

Implementations

impl ResolveConfig

pub fn new() -> ResolveConfig

Return a default, empty configuration.

pub fn ignore_char(&mut self, c: char) -> &mut ResolveConfig

Ignore a character when hashing migrations.

The migration SQL string itself will still contain the character, but it will not be included when calculating the checksum.

This can be used to ignore whitespace characters so changing formatting does not change the checksum.

Adding the same char more than once is a no-op.

Note: Changes Migration Checksum

This will change the checksum of resolved migrations, which may cause problems with existing deployments.

Use at your own risk.

pub fn ignore_chars( &mut self, chars: impl IntoIterator<Item = char>, ) -> &mut ResolveConfig

Ignore one or more characters when hashing migrations.

The migration SQL string itself will still contain these characters, but they will not be included when calculating the checksum.

This can be used to ignore whitespace characters so changing formatting does not change the checksum.

Adding the same char more than once is a no-op.

Note: Changes Migration Checksum

This will change the checksum of resolved migrations, which may cause problems with existing deployments.

Use at your own risk.

pub fn ignored_chars(&self) -> impl Iterator<Item = char>

Iterate over the set of ignored characters.

Duplicate chars are not included.
